Polished Brass Mortise Lockset

The Marks USA New Yorker 9NY92DW/3 is a right-hand mortise lockset finished in solid polished brass. It uses a vestibule function that stays locked from the outside and includes a cylinder with two keys. The latch-only design omits a bolt and rocker for specific door configurations. Commercial-grade components suit heavy-traffic doors.

Sustained commercial operation

Thru-bolted screwless lever plates and independent spring-loaded captivated spindles resist loosening under repeated use. Lever support springs return the handle positively after each cycle. The ADA-compliant angled escutcheon plates meet accessibility requirements for public buildings. Solid brass construction withstands constant handling without finish wear.

Latch-only vestibule function

This lockset provides a latch only, with no deadbolt or rocker mechanism included. The outside cylinder operates the latch while the inside has no thumb turn, keeping the door secured from the exterior at all times. Buyers needing a deadbolt or privacy function must select a different configuration.

Questions about this item

How loud is the 9NY92DW/3 mortise lock during daily use?

The lock operates mechanically with no motor or electronics, so it produces only the normal click of the latch engaging and the key turning in the cylinder.

What door preparation is required before installing this right-hand mortise lockset?

A standard 2-1/2 inch backset mortise pocket and a 1-1/16 by 7-5/8 inch face-plate cutout are needed, plus through-bolt holes for the screwless lever plates.

Will the polished brass lever and cylinder match older brass hardware already on the door?

The lockset uses solid polished brass for the escutcheon plates, lever and cylinder, so it will coordinate with existing polished brass trim of the same finish.
