PDQ I1274201 – Frequently Asked Questions
1) What is the PDQ I127-4201 cam used for?
I127-4201 is a Corbin cloverleaf cam for a PDQ conventional mortise cylinder. The cloverleaf profile is the one PDQ uses on MR Series mortise locks, so this is the cam you fit when a mortise cylinder has to drive an MR Series lock body. It is a replacement part, not a complete cylinder.
2) Will the I127-4201 cloverleaf cam work on a PDQ interchangeable core housing, or only a mortise cylinder?
The I127-4201 is specified for a conventional mortise cylinder. PDQ's cam range covers conventional mortise cylinders plus small format and large format IC housings, but which housings a given cam fits depends on the part number, and this one is the conventional mortise cylinder version. If you are retrofitting an SFIC or LFIC housing, order the cloverleaf cam built for that housing instead.
3) I have a PDQ KT Series deadbolt, is the cloverleaf cam the right one?
No. KT Series deadbolts take the Adams Rite AR cam, not the Corbin cloverleaf. The cloverleaf (I127-4201) is for MR Series mortise locks. Order the AR cam for the deadbolt.
4) Which cam do I need for PDQ 6W Series exit device trim?
6W Series wide stile escutcheon exit device trim uses the straight cam, not the cloverleaf. Keep I127-4201 for MR Series mortise locks and order the straight-cam version for the 6W trim.
5) What other cam profiles does PDQ offer besides the Corbin cloverleaf?
Alongside the Corbin cloverleaf, PDQ lists the Adams Rite AR cam, a straight cam, and Schlage, Sargent standard and Lockwood cams. One caveat for a locksmith standardizing a job: the Sargent standard and Lockwood cams are offered for conventional mortise cylinders and small format housings only, so they are not an option on large format IC housings.
6) Does the I127-4201 cam come keyed, or do I need a cylinder too?
This is the cam only, a replacement part in PDQ's Cylinders and Cores line. It does not include a cylinder, plug, keys or pins. If you need a working mortise cylinder, order the cylinder and use this cam to set it for a cloverleaf application.
7) Is this PDQ cam a genuine part suitable for commercial openings?
It is a genuine PDQ part, manufacturer number I127-4201, and PDQ classifies it as commercial door hardware. For a property manager or MRO buyer standardizing mortise cylinders across a building, using the factory cam keeps the cylinder-to-lock engagement as PDQ built it.
