Solid Brass Mortise Cylinder for Marks Metro

This polished brass mortise cylinder replaces the core on compatible Marks Metro locksets. It uses a six-pin tumbler mechanism and is keyed different with two cut keys supplied. The cylinder fits 1-1/8 inch mortise housings and carries a heavy-duty security rating. It is built for both interior and exterior door applications.

Standard Cam Design Allows Re-keying and Cam Swaps

The cylinder ships with a standard cam that operates entrance, vestibule, storeroom, office vestibule and classroom functions. Its solid brass body resists wear and the cam can be exchanged to suit other mortise lock configurations. Re-keying is possible without removing the lockset from the door. Installation simply threads the cylinder into the existing mortise housing.

Verify Your Lockset Model Before Ordering

Compatibility is limited to the Marks Metro 91, 114 and 71 series mortise locksets listed in the specifications. Cylinders for other brands, other Marks series or different thread sizes will not fit. Doors requiring a cylinder length other than 1-1/8 inch need a different model. Buyers who need master-keyed or keyed-alike cylinders must select a separately configured unit.

Questions about this item

How does the 1-1/8" mortise cylinder thread standard affect which Marks locksets it fits?

The cylinder threads into Marks Metro 91, 114, and 71 series locksets listed in the specifications, using the standard cam supplied.

What door thickness and cam clearance does the 2161 cylinder need to sit flush in a Metro mortise lock?

It is a 1-1/8" solid brass cylinder; verify your door thickness matches that length and that the standard cam clears the lock body.

What is the correct order to install the cylinder, cam, and set screw so the key turns smoothly?

Insert the cylinder, align the standard cam with the lock’s retractor, then tighten the set screw; test both keys before closing the door.
