Left-Hand Mortise Entry Lock

The Marks USA 7NY10A/26D-LH is a left-hand mortise lockset built for entry doors. Satin chrome plates and screwless, thru-bolted knobs give a clean finish. It suits commercial or heavy-residential doors that need a wide face plate and a solid brass cylinder supplied with two keys.

2-3/4 Inch Backset Constraint

This lockset requires a 2-3/4 inch backset preparation. The one-inch deadbolt throw and scissor latch with anti-friction latch only work when the door is cut to that dimension. Installers must verify the existing mortise pocket matches before fitting.

Thru-Bolted Knobs And Wide Face Plate

Thru-bolted mounting secures the knobs through the door thickness, reducing wobble over time. The 1-1/4 by 8 inch wide face plate covers a larger cut-out and distributes load across the stile. Screwless exterior knobs mean no exposed fasteners to loosen or snag.

Questions about this item

Should I choose the left-hand or right-hand version of this mortise lock?

The 7NY10A/26D-LH is the left-hand model; select it when the hinges are on the left as you face the door from outside.

What does the 2-3/4 inch backset mean once the lock is installed?

It places the centre of the key cylinder 2-3/4 inches from the door edge, so the mortise pocket must be cut at that distance.

How does the screwless thru-bolted design affect the mounting?

The knobs fasten through the door with concealed bolts, giving a clean face with no visible screws on either side.
