Marks USA Metro 116A/3 Polished Brass Right Hand Mortise Door Lock

Mortise Lockset for Right-Hand Doors

The Marks USA Metro 116A/3 is a mortise entry lockset finished in polished brass and built for right-hand doors. It uses a thru-bolted, screwless angled lever escutcheon plate assembly with independent spring-loaded captivated spindles and lever support springs. The solid brass cylinder operates with a key outside and a thumb turn inside and ships with two keys. Commercial-grade construction suits high-traffic entrances.

Mechanical Operation and Feel

Spring-loaded captivated spindles return the lever automatically after each use, reducing sag over time. The screwless escutcheon plates mount cleanly without visible fasteners on the finished surface. A one-inch deadbolt throw engages positively when the key or thumb turn is rotated. No electronic components or batteries are involved, so operation stays consistent regardless of power status.

ADA-Compliant Lever Access

The lever design meets ADA requirements for accessible hardware, allowing one-handed operation without tight grasping, pinching or twisting of the wrist. Buyers who need a left-hand configuration or a non-ADA knob style should select a different model. The lock is keyed different from the factory; projects requiring multiple cylinders on the same key will need a locksmith to re-key.
