Marks USA Satin Chrome Mortise Lockset

This new Marks USA mortise lockset delivers a vestibule storeroom function where the outside cylinder controls entry and the inside knob remains rigid with no thumb turn. It is intended for commercial doors that must stay locked from the exterior at all times.

Left Hand Screwless Knob Installation

The lockset arrives with thru-bolted screwless knobs that mount through the door without exposed fasteners on the trim. Installers must confirm the door is prepared for a left-hand mortise pocket and a 2-1/2 inch backset before fitting the 1-1/16 by 7-5/8 inch face plate.

Latch Only Configuration Decides Fit

This unit supplies a latch bolt only and omits the deadbolt and rocker assembly entirely. Buyers who need a deadbolt for secure locking or a privacy function with interior release cannot use this lockset.

Questions about this item

How do I confirm the latch retracts smoothly and the outside knob stays locked after installing the 9NY10DW/26D?

Operate the outside knob with a key — the solid brass cylinder should turn, retract the latch, and spring back when released; the knob remains locked without a key, and the inside has no thumb turn, so it cannot be unlocked from that side.

What components come with the 9NY10DW/26D and what must I supply?

The set includes the mortise lock body with 2-1/2 backset, 1-1/16" x 7-5/8" face plate, screwless through-bolted knobs, solid brass cylinder and two keys; you must provide mounting screws and a strike plate.

Which handing should I select for a door that swings into the room with hinges on the left?

Choose the Left Hand version (9NY10DW/26D LH) — it matches a door hinged on the left when viewed from the outside, and the satin chrome finish is the same across all handings.
