PDQ I0251 – Frequently Asked Questions
1) What does the PDQ I0251 dust box actually do, and is it the same as a strike plate?
The I0251 is the dust box, not the strike. It is the sheet metal cup that sits behind the strike plate in the mortised pocket of the frame, keeping debris out of the latch hole and giving the latchbolt a clean throw. You still need the T strike plate itself; the dust box is the part that lines the hole behind it. PDQ lists a matching dust box for each strike style: T strike, ASA (ANSI) strike and full lip strike.
2) Will the PDQ I0251 dust box work with an ASA strike instead of a T strike?
No. The I0251 is sized for the T strike specifically. PDQ pairs each strike style with its own dust box, so an ASA (ANSI) strike or a full lip strike takes its own matching box. Order the dust box that goes with the strike style already prepped in your frame.
3) I'm standardizing strike prep across a building with PDQ GT locks. Can I order the dust box on its own?
Yes, I0251 is sold as an individual genuine PDQ part, so you can stock dust boxes separately from strikes, latchbolts or levers. For a property manager or MRO buyer keeping a parts bin, that means you can carry the T strike dust box in quantity without buying complete lock sets. It is a commercial door hardware part, consistent with the GT and XGT commercial cylindrical line.
4) What else do I need to finish a PDQ GT latch and strike replacement besides the dust box?
The latch side and the frame side are separate parts. PDQ's GT and XGT parts range covers the standard latchbolt with dead latch and a 2-1/4 x 1-1/8 inch square corner faceplate, the strike plates themselves, and an installation screw pack with mounting screws, hex key and pick. If you're also swapping the lock body trim, levers in Boston, Miami and Philadelphia styles, inside and outside roses, push buttons and cylinder tailpieces are all available as separate parts.
5) I'm installing a PDQ GT lock on a 1-3/8 inch door. Is there a part for that?
Yes, PDQ offers a spacer set for 1-3/8 inch doors in the GT and XGT parts range. That is a lock-side item and separate from the I0251 dust box, which is a frame-side part and unaffected by door thickness. Also in the installation group is a boring jig for the anti-rotation through-bolts and lever return springs.
6) Do I need a dust box at all, or can I leave the strike pocket bare?
Mechanically the lock will latch without one, but the dust box is what keeps the mortised pocket clean and prevents the latchbolt from fouling on debris or frame insulation. On a replacement where the original box is crushed, rusted or missing, dropping in the I0251 behind the T strike restores the original prep. It is the part most often lost during a strike swap.
