Mortise lock with vestibule function

The Marks Metro 114DW/3 is a left-hand mortise lockset finished in polished brass. It operates as a storeroom function with a latch only and no deadbolt or rocker. The lock is through-bolted with screwless knobs and a self-adjusting spindle for secure installation. A solid brass cylinder with two keys is included.

Suited for single-entry secure rooms

This lock fits doors needing keyed entry from the outside with no interior thumb turn, typical for storage or utility rooms. It is not suitable for doors requiring a deadbolt, a privacy turn, or a right-hand configuration. Buyers needing a passage or privacy function should look at a different lock type.

2-1/2 inch backset dimension

The lock has a fixed backset of 2-1/2 inches, which must match the door preparation exactly. The face plate measures 1-1/16 by 7-5/8 inches and requires a matching mortise pocket. Verify these dimensions before ordering to ensure the lock will fit the door.

Questions about this item

What door thickness does the 114DW/3's self-adjusting spindle accommodate?

The screwless knobs use a self-adjusting spindle that fits standard commercial door thicknesses without extra parts.

Will the 2-1/2" backset align with my existing mortise pocket?

The 2-1/2" backset matches the most common commercial mortise prep; verify your pocket depth before installing.

How do I confirm the storeroom function is operating correctly after fitting?

The outside knob stays rigid, the latch retracts only with the key, and the inside knob always opens freely.
