Polished Brass Mortise Entry Lock

The Marks USA New Yorker 9NY92A/3 is a new mortise lockset finished in polished brass. It is built for commercial or residential entry doors that require a heavy-duty, ADA-compliant lever handle. The unit ships with a solid brass cylinder and two keys.

Left-Hand Thru-Bolted Assembly

This model is handed for left-hand doors only and uses thru-bolted, screwless angled lever escutcheon plates. Independent spring-loaded captivated spindles and lever support springs ensure smooth, reliable operation and secure lever retention over time.

Suits ADA-Compliant Left-Hand Doors

Buyers fitting a left-hand entry with a 2-1/2 inch backset and 1 inch deadbolt will find the correct hardware here. Those needing a right-hand configuration, a different backset, or a non-mortise installation should look at other lock types.

Questions about this item

What does the 2-1/2" backset mean when the lock is fitted to a door?

It places the centre of the cylinder 2-1/2 inches from the door edge, so the mortise pocket and strike must align with that dimension.

How does the mortise lock interface with the door and frame in practice?

The 1-1/16" x 7-5/8" front face plate mortises into the door edge, while the 1" deadbolt throws into a matching strike cut-out in the frame.

What physical preparation does the thru-bolted screwless lever assembly require on the door?

The door needs through-holes for the thru-bolts that clamp the escutcheon plates, plus the standard mortise pocket for the lock body and cylinder.
