PDQ I54221 – Frequently Asked Questions
1) What does the PDQ I54221 cam fit?
The I54221 is a Schlage-profile cam for PDQ large format interchangeable core housings. It is the tailpiece that drives the lock, not a cylinder or core itself, so you order it when the housing is good but the cam is wrong profile, damaged, or missing.
2) Will the I54221 Schlage cam work on a PDQ small format core housing or a conventional mortise cylinder?
No. The I54221 is the large format housing version. PDQ offers Schlage cams for conventional mortise cylinders and small format housings as well, but those are separate part numbers, so match the cam to the housing type you actually have.
3) I have PDQ KT Series deadbolts and MR Series mortise locks, is the Schlage cam the right one?
Not for those. PDQ KT Series deadbolts use the Adams Rite AR cam, and MR Series mortise locks use the Corbin cloverleaf cam. The 6W Series wide stile escutcheon exit device trim takes the straight cam. The I54221 Schlage cam is for hardware prepped for a Schlage cam profile.
4) Do I need anything else besides the cam when I order a PDQ large format IC housing setup?
The I54221 is the cam only. You still need the large format housing and the interchangeable core itself, plus keying. PDQ publishes a cylinder, core and keying brochure and an architectural submittal sheet covering how those pieces are specified together.
5) Is the PDQ I54221 cam a genuine PDQ part or an aftermarket copy?
It is a genuine PDQ part, manufacturer part number I54221. For a facility standardized on PDQ cylinders and cores, using the factory cam keeps the keying and core housing combination the way PDQ specifies it.
6) Is this PDQ cam rated for commercial door hardware use?
Yes, the I54221 cam is a commercial door hardware part, intended for PDQ cylinder and core applications in commercial openings rather than residential sets.
