Mortise Entry Lock for Commercial Doors

The Marks USA 9NY92A/26D is a heavy-duty mortise lockset built for institutional and industrial entrances. Its Grade 2 security rating and brass construction suit high-traffic doors that require reliable access control. The left-hand configuration and ADA-compliant lever trim meet accessibility requirements for public buildings.

2-1/2 Inch Backset with One-Inch Deadbolt

The lock fits a standard 2-1/2 inch backset preparation and throws a one-inch deadbolt for strong latch engagement. A solid brass five-pin cylinder on the exterior and a thumb turn on the interior provide keyed-different access for individual door control. This combination handles daily commercial use but is not intended for high-security master-keyed systems.

Screwless Thru-Bolted Lever Plates

Thru-bolted screwless lever assemblies with independent spring-loaded captivated spindles prevent lever sag and simplify installation on metal or wood doors. Lever support springs add durability under repeated operation. The satin chrome finish on solid plates resists wear in institutional environments, though the handed design limits use to left-hand door swings only.

Questions about this item

Will the 2-1/2" backset and 1-1/16" x 7-5/8" face plate match the mortise pocket cut for my existing Marks hardware?

The lock uses a 2-1/2" backset and a front face plate measuring 1-1/16" x 7-5/8", which are standard dimensions for the Marks New Yorker series mortise prep.

How can I confirm the deadbolt and lever action are operating correctly after installation?

Test the 1" deadbolt throw with the key outside and thumb turn inside; the lever should retract the latch smoothly with the independent spring-loaded captivated spindles and return firmly via the lever support springs.

Does the box include the cylinder and keys, or do I need to order a separate 5-pin cylinder for the entrance function?

The set includes a solid brass 1-1/8" 5-pin cylinder finished in satin chrome with two keys, so no separate cylinder purchase is required for keyed-different operation.
