Mortise entry lock with thru-bolted knobs

The Marks Metro 114A/3 is a solid brass mortise entry lockset finished in polished brass. It uses a 2-1/2" backset and a 1" deadbolt throw. Through-bolted plate assemblies and screwless knobs with a self-adjusting spindle secure the trim without exposed screws. A solid brass cylinder and two keys are included.

Right-hand doors needing a through-bolted entrance

This lock fits right-hand doors prepared for a standard mortise pocket and a 1-1/16" x 7-5/8" face plate. It suits commercial or residential entrances where a durable brass cylinder and thru-bolted knobs are specified. Left-hand doors, cylindrical bore preparations, or electronic access control requirements are not addressed by this model.

2-1/2" backset determines fit

The 2-1/2" backset is the critical dimension that decides whether this mortise lock aligns with existing door prep. Verify the measurement from the door edge to the centre of the spindle hole before purchase.

Questions about this item

How do I confirm the mortise lock is working correctly after installation?

Operate the solid brass cylinder from the outside and the thumb turn from the inside; the 1 inch deadbolt should extend and retract smoothly, and the screwless knobs with self-adjusting spindle must turn freely in both directions.

What components are included in the box and what must be purchased separately?

The box contains the right-hand mortise lock body, solid brass front face plate measuring 1-1/16 by 7-5/8, thru-bolted knob assemblies, solid brass cylinder and two keys; no additional parts are required for a standard entrance installation.

Which version of the Marks Metro 114A/3 should I choose for a right-hand door with a 2-1/2 inch backset?

Select the Polished Brass Right Hand model 114A/3, which is built for a 2-1/2 inch backset and provides entrance function with a 1 inch deadbolt, through-bolted knobs and a solid brass cylinder.
