Installation Quality Control
- Confirm opening number, handing, fire rating, and hardware set before installation begins
- Verify frame is plumb, square, and secure before hanging door slab
- Check hardware installation against approved submittal — item, finish, and mounting location
- Test self-closing operation: door closes and latches fully from 90° open position
- Verify clearances: undercut, top gap, and side gaps are within NFPA 80 tolerances on rated openings
- Record QC status and any field deviations by opening number before releasing to next trade
