Job Overview
This project qualifies you to lay out and install pulls and knobs on a controlled cabinet set using repeatable templates and clean, supported drilling. The finished work product is a completed set of cabinet doors and drawer fronts with hardware installed at consistent locations, orientation, and spacing across the entire run, inspected against the approved hardware schedule and elevation. This project depends on the aligned, fully adjusted doors and drawer fronts completed in Project 12 and produces the final cosmetic and functional hardware condition carried into the Chapter 20 capstone punch inspection.
You will review the approved hardware schedule and elevation, confirm every door and drawer front is fully aligned, build or select a rigid template, test the template on matching scrap, drill and install hardware working from consistent reference edges, check alignment across adjacent doors and drawers after each group, correct template drift before continuing, and inspect the finished spacing, orientation, finish condition, and fastener engagement of every installed piece.
This project assumes the cabinet doors, drawer fronts, hinges, and slides installed and adjusted in Project 12 are complete, aligned, and operating correctly before any hardware hole is drilled. It sits immediately after Project 12 and immediately before the Chapter 19 repair project, which corrects any hardware condition that develops after installation, and before the Chapter 20 capstone, which integrates this project's hardware installation into the complete cabinet system.
Skills You Will Demonstrate
- CB-073 — Create or select a rigid hardware template matching the approved hardware style, size, center-to-center spacing, and orientation.
- CB-074 — Mark hardware locations on each door and drawer front from the approved cabinet type, top, bottom, left, right, door, and drawer references.
- CB-075 — Drill clean, perpendicular, supported hardware holes at the marked locations without breakout or finish damage.
- CB-076 — Install pulls and knobs with the correct screws and washers, tightened securely without crushing the door or drawer face.
- CB-077 — Maintain consistent spacing, orientation, and reference-edge use across every door and drawer front in the cabinet set.
- CB-078 — Inspect hardware alignment, spacing, finish protection, screw engagement, and operation across the completed set.
Where This Skill Fits
This project depends directly on Project 12: a door or drawer front that is not fully aligned before hardware drilling will carry that misalignment into every hardware hole drilled from it, and a template built or tested before Project 12's adjustments are final will drift as soon as doors are re-hung. The reference-edge discipline used here — marking every hardware location from the same top, bottom, left, right, door, and drawer references rather than by eye — is the same discipline the Chapter 19 repair project relies on when tracing a misaligned pull back to an inconsistent reference edge or an untested template.
The finished hardware set produced here is the last cosmetic and functional installation step before the Chapter 20 capstone's final punch inspection, which checks appliance clearances, door swings, drawer extension, and every moving and non-moving cabinet component together.
Scope and Intended Use
This project covers:
- reviewing the approved hardware style, size, center-to-center spacing, orientation, location, and accessibility requirements
- confirming that doors and drawer fronts are fully aligned before drilling begins
- creating or selecting a rigid hardware template and testing it on scrap matching the cabinet material
- verifying screw length through the scrap assembly before installing any hardware in a finished face
- clamping the template, marking hole centers, supporting the back face, and drilling perpendicular, supported holes
- installing pulls and knobs with the correct screws and washers, tightened securely without crushing the face
- repeating installation using the same reference edges and checking alignment across adjacent doors and drawers after each group
- correcting template drift before continuing and inspecting spacing, orientation, finish protection, screw engagement, and operation
This project does not authorize the learner to:
- select hardware style, size, center-to-center spacing, or location independently of the approved hardware schedule and elevation
- drill a hardware hole in a finished door or drawer front before the template has been tested on matching scrap and the screw length has been verified
- enlarge a misdrilled hole to hide a layout error unless the specific hardware system permits it
- substitute a longer or different-diameter screw than the one specified for the hardware and substrate
Any hardware location that conflicts with the approved schedule, or a substrate condition that will not support the specified screw, must stop drilling in that location until direction is obtained.
Reference Conventions
Establish these references before any marking or drilling begins, and do not change them once hardware installation has started on a given cabinet run.
| Term | Definition |
|---|---|
| Reference edge | The consistent door, drawer, top, bottom, left, or right edge from which every hardware template placement in this project is measured |
| Center-to-center spacing | The approved distance between mounting-screw centers for a two-hole pull, as stated in the hardware schedule |
| Template drift | A progressive shift in hardware hole location caused by an inconsistent reference edge, a loosened template, or an uncorrected marking error carried from one door or drawer front to the next |
| Waste side | The face and area of the door or drawer front where breakout, chip-out, or overcut is acceptable only within the hardware system's permitted trim method |
| Backer block | A sacrificial piece of matching or compatible material held against the back face of a door or drawer front to reduce breakout during drilling |
| Hardware schedule | The approved document specifying hardware style, size, center-to-center spacing, orientation, and location for every door and drawer front in the project |
Hardware Installation Reference Record
Before beginning any marking, record the controlling references directly on the hardware installation record:
Cabinet run / area ID: ______ Hardware schedule reference: ______ Hardware style and center-to-center spacing: ______ Screw type and length verified on scrap: ______
Date started: ____________ Installer name: ____________
Prerequisites
- Every cabinet door and drawer front installed, aligned, and fully adjusted under Project 12, including reveal consistency and hinge and slide operation
- The approved hardware schedule and elevation available on site, current and confirmed against the cabinet schedule
- Pulls or knobs, mounting screws, and washers for the full cabinet set on hand and matched to the schedule
- Scrap material matching each door or drawer-front substrate available for template testing
- A hardware installation record available for field entries
Common Field Fundamentals
Every hardware installation in this book, whether a single knob or a full cabinet set, follows the same order: confirm the approved schedule, confirm the doors and drawers are ready, build and test a rigid template, mark and drill from consistent references, install and tighten the hardware, and check alignment across the group before continuing. Learning that sequence here protects every hardware installation performed later in this book and during the Chapter 19 repair project.
Schedule reviewHardware style, spacing, orientation, and location confirmed against the approved schedule
Template build and testRigid template built or selected and verified on matching scrap before any finished face is drilled
Mark and drillHole centers marked and holes drilled clean, perpendicular, and supported
Install and inspectHardware installed and tightened, then checked for spacing, alignment, and operation across the set
Separating Reference-Edge Errors From Substrate or Screw Errors
Every hardware defect found during this project traces to one of two causes: an inconsistent reference edge or template position, or an incompatible screw length or substrate condition. A pull that lands at a different height than its neighbor is a reference-edge or template-drift problem, correctable by rechecking the template against the marked reference edges before the next hole is drilled. A screw that bottoms out before drawing the hardware tight, or that pushes through a finished face, is a screw-length or substrate problem, correctable only by verifying the screw length against the actual door or drawer-front thickness on scrap before continuing.

Layout / Drilling / Hardware-Installation Qualification
Cabinet Pull and Knob Installation
A. Finished-Project Specification
Scope: one completed hardware installation covering every door and drawer front identified on the approved hardware schedule for one cabinet run or cabinet set, using a single tested template and consistent reference edges.
B. Required Documentation Schedule
| Document | Source | Confirmation Required |
|---|---|---|
| Hardware schedule | Designer / cabinet supplier | Style, size, center-to-center spacing, orientation, and location confirmed for every door and drawer front |
| Cabinet elevation | Designer / plan set | Hardware location confirmed against door and drawer-front position and adjacent cabinet spacing |
| Accessibility requirement, where applicable | Authority having jurisdiction / approved plan | Hardware type and mounting height confirmed against the applicable requirement |
| Project 12 alignment record | Prior project documentation | Door and drawer-front alignment and operation confirmed complete before drilling |
C. Preparation Materials and Consumables
- Hardware: pulls or knobs, mounting screws, and washers as specified in the approved hardware schedule, sufficient for every door and drawer front in the cabinet set.
- Template stock and test scrap: a rigid template matched to the specified center-to-center spacing, and scrap material matching each door or drawer-front substrate for test drilling and screw-length verification.
- Documentation: one hardware installation record per cabinet run or area as required by the project specification.
D. Acceptance Standards
| Check | Standard |
|---|---|
| Hardware style and spacing | Matches the approved hardware schedule for every installed piece |
| Hole location and orientation | Marked and drilled from the consistent reference edges established by the tested template |
| Hole quality | Clean, perpendicular, and free of breakout or finish damage on both faces |
| Screw engagement | Verified length seats the hardware and washer securely without penetrating the finished face or crushing the substrate |
| Alignment across the set | Consistent height, side spacing, and orientation confirmed across adjacent doors and drawer fronts |
| Documentation completeness | Template test, screw-length verification, and final hardware inspection are recorded on the hardware installation record |
E. Schedule Review and Readiness Confirmation (Steps 1–2)
- Review the approved hardware style, size, center-to-center spacing, orientation, location, and accessibility requirements. Confirm the hardware schedule revision matches the current cabinet plan and elevation before proceeding.
- Confirm doors and drawer fronts are fully aligned before drilling. Verify the Project 12 alignment record shows completed reveal consistency and hardware operation for every door and drawer front in the cabinet set.
F. Template Creation and Verification (Steps 3–7)
- Create or select a rigid hardware template. Confirm the template's center-to-center spacing and hole diameter match the approved hardware schedule.
- Mark cabinet type, top, bottom, left, right, door, and drawer references on the template. Use the marking pencil to record every reference the template will be positioned against.
- Test the template on scrap matching the cabinet material. Mark, drill, and install a sample piece of hardware on the scrap before drilling any finished face.
- Verify screw length through the scrap assembly. Confirm the specified screw seats the hardware and washer securely without penetrating the opposite face.
- Clamp the template to the first door or drawer front. Align the template's marked references against the door or drawer front's actual top, bottom, left, and right edges.
G. Marking and Drilling (Steps 8–13)
- Confirm the marked position against the approved elevation. Check the template's position against the hardware schedule and elevation before marking hole centers.
- Mark hole centers with an awl or approved punch. Mark each hole center firmly enough to prevent bit wander during drilling.
- Support the back face with a sacrificial block to reduce breakout. Position the backer block directly behind each marked hole center before drilling.
- Drill perpendicular holes using the specified bit. Hold the drill square to the face and drill to the depth required for the specified fastener.
- Drill from both faces only when the approved material method requires it. Follow the specified drilling method for the door or drawer-front substrate; do not drill from both faces unless the method requires it.
- Clean chips without scratching the finish. Use the vacuum or brush to remove chips before installing hardware.
H. Installation, Repetition, and Inspection (Steps 14–21)
- Install the pull or knob with the correct screws and washers. Confirm the screw and washer match the hardware schedule before installing.
- Tighten securely without crushing the door or drawer face. Stop tightening once the hardware is snug and fully seated against the face.
- Repeat using the same reference edges. Position the template against the same top, bottom, left, and right references for each subsequent door and drawer front.
- Check alignment across adjacent doors and drawers after each group. Compare installed hardware height and spacing against its neighbors before continuing to the next group.
- Correct template drift before continuing. Recheck the template against the marked reference edges if any installed piece is out of alignment with its neighbors.
- Do not enlarge holes to hide major layout errors unless the hardware system permits it. Identify and correct the reference-edge or template error before drilling additional holes.
- Inspect spacing, orientation, finish protection, screw engagement, and operation. Confirm every installed piece against the Acceptance Standards table.
- Document template dimensions and hardware locations. Record the final template dimensions and any correction on the hardware installation record.
Common Verification Inspection
Inspect the completed hardware installation using the same checks regardless of which cabinet run or set it covers.
- Schedule check: confirm installed hardware style, spacing, orientation, and location match the approved hardware schedule and elevation.
- Reference check: confirm every hole was marked and drilled from the same tested template and reference edges.
- Hole-quality check: confirm holes are clean, perpendicular, and free of breakout or finish damage on both faces.
- Fastener check: confirm the verified screw length and specified washer are installed and fully seated without crushing the substrate.
- Alignment check: confirm consistent height, side spacing, and orientation across every door and drawer front in the set.
- Documentation check: confirm the template test, screw-length verification, and final inspection are recorded on the hardware installation record.

Project Closeout
You have completed the thirteenth project in the cabinet-installation sequence: installing cabinet pulls and knobs accurately. This project required you to create or select a rigid hardware template (CB-073), mark hardware locations from consistent references (CB-074), drill clean, supported holes (CB-075), install pulls and knobs securely (CB-076), maintain consistent spacing and orientation across the cabinet set (CB-077), and inspect the completed hardware installation (CB-078).
You now have a cabinet set with hardware installed at consistent, inspected locations across every door and drawer front. That result carries directly into the next project: building and installing open utility shelving supported by structural cleats or listed brackets.
Protect the tested template, verified screw length, and reference-edge records established in this project. The Chapter 19 repair project relies on these records to trace and correct any hardware defect that develops after installation.
