Inspection Setup and Traceability

Door or frame identifier matches shop drawing / hardware schedule

Record the unique identifier, opening number, or part number and confirm it matches the approved drawing or hardware schedule.

Inspection tools verified and suitable for measurement critical (required)

Confirm required tools are available and appropriate for the measured features, such as calipers, tape, bore gauge, depth gauge, and square.

Yes No N/A

Reference document available at point of use

Enter the drawing revision, hardware template, or SOP used for this inspection.

Lock Bore and Edge Prep Dimensions

Lock bore diameter within specified tolerance critical (required)

Measure the main lock bore diameter and compare it to the approved hardware preparation requirement.

Backset dimension matches specified hardware prep critical (required)

Measure from the door edge to the bore centerline and verify it matches the required backset.

Cross-bore and edge-bore alignment is centered and square critical (required)

Verify the bore centerline is aligned to the door edge and the prep is not visibly out of square or offset.

Yes No N/A

Photo evidence (optional)

Edge bore diameter and depth match hardware requirements critical (required)

Measure the latch edge bore diameter and depth against the specified hardware prep.

Hinge Mortise and Door Edge Preparation

Hinge mortise location matches specified setback critical (required)

Measure hinge location from the top or bottom of the door and verify it matches the approved layout.

Hinge mortise depth and width are correct critical (required)

Measure mortise depth and width to confirm the hinge leaf seats flush without overcut or proud condition.

Door edge is free of tear-out, splintering, or breakout at prep locations

Inspect all machined prep areas for damage that would affect hardware fit or finish.

Yes No N/A

Photo evidence (optional)

Strike Prep and Frame Alignment

Strike prep location matches frame layout critical (required)

Measure the strike cutout location and verify it aligns with the latch centerline and approved frame prep.

Strike opening dimensions match specified hardware critical (required)

Measure strike opening width, height, and depth as applicable for the installed hardware set.

Frame prep is clean, square, and free of obstruction

Verify the frame cutout is free of burrs, debris, deformation, or interference that would prevent proper strike installation.

Yes No N/A

Fit Verification and Disposition

Trial fit confirms hardware seats without interference critical (required)

Perform a dry fit or template check where applicable to confirm the lockset, latch, hinges, and strike can be installed without binding.

Yes No N/A

Photo evidence (optional)

All dimensional non-conformances documented critical (required)

Record any deficiency, measured deviation, and disposition such as rework, hold, or accept-as-is with approval.

Inspector approval for release to installation critical (required)

Inspector signs to confirm the door or frame prep is acceptable for release.
