Description
The Marks USA 9NY10A is a commercial-grade mortise lockset designed for interior doors in office buildings, hotels, and multi-tenant facilities. Its cast zamac body with baked enamel finish resists corrosion, while the 1-inch cast alloy deadbolt and reversible 1/2-inch brass latch provide reliable security without requiring expensive Grade 1 fire ratings.
This lockset fits standard 2-1/2-inch backset preparations and works with Marks C-keyway cylinders. Installation features thru-bolted knob assemblies and a flexible faceplate that mounts flat or at 3 degrees. Contact an E.D. Locks security specialist at sales@edlocks.com or 1-877-207-6067 for keying options, finish selection, and expert guidance on knob and lever configurations for your specific application.
