Right-Hand Mortise Entrance Lock

The Marks Metro 114A/3-X is a mortise lockset designed for right-hand doors in entrance applications. It operates with a cylinder on the exterior and a thumb turn on the interior. The unit is supplied with two keys and features a 2-1/2 inch backset.

Solid Brass Through-Bolted Construction

Solid brass plates and a solid brass cylinder form the core of the lock body. Knob assemblies are through-bolted for a rigid mechanical connection to the door. Self-adjusting spindles work with screwless knobs to maintain alignment during daily operation.

Wide Face Plate and Deadbolt Dimensions

The front face plate measures 1-1/4 inches by 8 inches, covering a broad mortise pocket. A one-inch throw deadbolt engages the strike for secure locking. The wide plate suits commercial door preparations where a larger front is specified.

Questions about this item

How is the mortise lock body installed into the door pocket and which step is most often missed?

The lock body fits into a mortise pocket cut to accept the 1-1/4" x 8" wide front plate; the step most often missed is securing the through-bolted knob assemblies before testing the deadbolt throw.

What maintenance or replacement will the solid brass cylinder and its two keys require over time?

The solid brass cylinder should be lubricated periodically with graphite powder; if the keyway wears or a key is lost, the cylinder can be rekeyed or replaced without changing the mortise body.

What is the first limitation that appears under sustained use of the 1" deadbolt on a right-hand door?

The 1" deadbolt throw is the limiting factor; on a right-hand door the bolt engages the strike at its full extension, so frame alignment must stay precise to prevent binding.
