Marks Metro Mortise Entry Lock

The Marks Metro 114A/3-X is a mortise entry lockset finished in polished brass and configured for left-hand doors. It is intended for residential or commercial entrances that require a keyed exterior and thumb-turn interior operation.

Capacity and headroom

The lockset uses a 2-1/2 inch backset and a 1 inch deadbolt throw, fitting standard mortise preparations with a 1-1/4 by 8 inch face plate. It is not suited for doors prepped for cylindrical locksets or for right-hand swing applications.

Build quality and connectors

Solid brass plates and a solid brass cylinder provide durable construction, while through-bolted knob assemblies and self-adjusting screwless knobs simplify installation and resist loosening over time. Two keys are included for the keyed-different cylinder.

Questions about this item

Will the 2-1/2" backset and 1-1/4" x 8" face plate match the mortise pocket cut for my existing door hardware?

This lockset uses a 2-1/2" backset and a 1-1/4" x 8" wide face plate. Measure your current mortise pocket depth and face plate dimensions to confirm they align with these specifications before installation.

How do I verify the left-hand orientation and thumb turn operate correctly after fitting the lock?

Install the lock on the door. From the exterior, the hinges should be on the left. Operate the outside knob with a key and the inside thumb turn; the 1" deadbolt should extend and retract smoothly in both directions without binding.

Does the box include the solid brass cylinder and two keys, or must they be ordered separately?

The lockset ships with the solid brass cylinder installed and includes two keys in the box. No separate cylinder or key purchase is required for standard keyed-different operation.
