PDQ I1274205 – Frequently Asked Questions
1) What is the PDQ I127-4205 cam used for?
The I127-4205 is the Adams Rite AR cam for a PDQ conventional mortise cylinder. The AR cam profile is what PDQ KT Series deadbolts require, so this is the piece you fit to a conventional mortise cylinder when it is going to drive a KT Series deadbolt.
2) Will the I127-4205 AR cam work on a PDQ interchangeable core housing, or only a conventional mortise cylinder?
This particular part is the conventional mortise cylinder version. PDQ offers replacement cams for conventional mortise cylinders and for both small format and large format interchangeable core housings, but which housings a given cam fits depends on the part. If you are keying an IC housing rather than a conventional mortise cylinder, order the AR cam built for that housing type instead of I127-4205.
3) My PDQ mortise lock won't turn with the cylinder I installed. Is the AR cam the right one?
Not for an MR Series mortise lock. PDQ MR Series mortise locks take the Corbin cloverleaf cam, not the Adams Rite AR profile. The AR cam (I127-4205) belongs on cylinders driving KT Series deadbolts. A cam that doesn't match the lock body will either not engage the hub or will bind, which is usually what a no-turn condition is.
4) Which PDQ cam do I need for 6W Series wide stile exit device trim?
The straight cam, not the AR. PDQ specifies the straight cam for 6W Series wide stile escutcheon exit device trim. The Adams Rite AR cam I127-4205 is for KT Series deadbolt applications. Same cylinder family, different cam profile.
5) What other cam profiles does PDQ offer besides the Adams Rite AR?
Alongside the Adams Rite AR cam, PDQ lists the Corbin cloverleaf, the straight cam, plus Schlage, Sargent standard and Lockwood profiles. Note that the Sargent standard and Lockwood cams are offered only for conventional mortise cylinders and small format housings, not large format.
6) Is this a genuine PDQ part or an aftermarket cam?
I127-4205 is a genuine PDQ replacement cam, manufacturer part number I127-4205, in PDQ's Cylinders and Cores line. For facilities standardized on PDQ cylinders it keeps the keying and cam geometry factory-correct.
7) Is the PDQ AR cam suitable for commercial door hardware use?
Yes. PDQ classes the I127-4205 cam as commercial door hardware, which is consistent with where it is used, PDQ conventional mortise cylinders serving KT Series deadbolts on commercial openings.
