PDQ I4587 – Frequently Asked Questions
1) What exactly is the PDQ I4587 part, and what does a dust box do?
I4587 is the deadbolt dust box for PDQ KT Series deadbolts. It's the cup that lines the bolt hole in the door frame, so the bolt drops into a finished pocket instead of raw wood or an open cavity. It's a genuine PDQ part and is ordered on its own, not with a bolt or strike.
2) Will the I4587 dust box work with a PDQ KT Series heavy duty deadbolt?
Yes. The dust box is part of the PDQ replacement set for the KT Series extra heavy duty deadbolt, alongside the bolt assemblies and the deadbolt strike. If your deadbolt is a PDQ KT, this is the matching dust box.
3) I'm replacing a PDQ deadbolt strike plate. Does the I4587 dust box come with the strike?
No. The dust box is a separate line item. The PDQ KT deadbolt strike is a 2-3/4 inch by 1-1/8 inch plate ordered under its own part number, so if you need both the strike and the pocket liner behind it, order them separately.
4) My PDQ deadbolt bolt is worn out, not the dust box. What do I order instead?
For the bolt itself, PDQ offers KT Series deadbolt bolt assemblies in 2-3/4 inch and 2-3/8 inch backsets, with faceplate choices of 2-1/4 x 1 inch square corner, 2-1/4 x 1 x 1/4 inch radius corner, or drive-in. Match the backset already bored in your door, then pick the faceplate style that matches the existing door prep. The I4587 dust box only addresses the frame side.
5) Do I need a dust box if the frame is hollow metal?
A dust box gives the bolt a closed pocket behind the strike, which is what matters most in a wood frame or a frame cavity that would otherwise collect debris. In hollow metal frames many shops still install it to keep the bolt hole clean and to stop the bolt bottoming on insulation or grout. If the original PDQ KT installation had one, replace it with I4587 so the strike sits the same way it did before.
6) I manage a building standardized on PDQ KT deadbolts. Can I stock this part for all of them?
Yes, that's the point of it. I4587 is the single dust box used across PDQ KT Series deadbolt installations, so one part number covers every KT opening in the building regardless of which backset or faceplate style the doors were bored for.
7) Is the PDQ I4587 dust box meant for commercial openings or residential doors?
It's a commercial door hardware part, supporting the PDQ KT Series extra heavy duty deadbolt. It will physically serve a residential frame, but it is specified for commercial use.
