Mortise Entry Lockset for Right-Hand Doors

This Marks New Yorker mortise lockset provides an entry function for right-hand doors. It features a polished brass finish with solid brass plates and a wide front face plate. The lockset includes a solid brass cylinder supplied with two keys for keyed-different access.

2-3/4 Inch Backset with Deadbolt and Dual Latches

The lock operates on a 2-3/4 inch backset and includes a one-inch deadbolt. It combines a scissor latch with an anti-friction latch for smooth operation. The cylinder is operated from the outside while a thumb turn controls the deadbolt from the inside.

Replaces Cylindrical Locks Requiring Mortise Pocket

This unit upgrades from standard cylindrical locksets where a mortise pocket already exists or can be cut. The screwless, thru-bolted knob design adds strength over surface-mounted hardware. It is not suited for doors prepped only for a 2-1/8 inch bore hole.

Questions about this item

Will the 2-3/4 backset on this mortise lock align with the existing door prep on my older door?

This lock uses a 2-3/4 backset and a 1-1/4 x 8 wide face plate; measure your current mortise pocket and edge bore to confirm they match these dimensions before installing.

How can I verify the deadbolt and latches engage correctly after fitting the lockset?

Operate the exterior key and interior thumb turn to throw the 1 deadbolt fully, then check that both the scissor latch and anti-friction latch retract smoothly when the screwless knobs are turned.

Does the package include the solid brass cylinder and keys, or must they be ordered separately?

The set ships complete with the solid brass cylinder and 2 keys included, along with the thru-bolted screwless knobs and wide face plate; no additional cylinder or keying components are required.
