Polished Brass Mortise Lockset

This Marks USA mortise lockset is a polished brass left-hand unit built for vestibule or storeroom doors. It operates with a single cylinder on the outside and no thumb turn on the inside, so the exterior knob stays locked until a key retracts the latch. The latch-only mechanism omits a deadbolt and rocker, matching the DW function profile. It fits interior or exterior doors from 1-3/8 to 1-3/4 inches thick.

Who should look elsewhere

Buyers who need a deadbolt for added security cannot use this lockset because it is latch only. Installers working on right-hand doors must verify handing before purchase, as this unit is configured for left-hand swing. Anyone wanting an interior thumb turn for keyless egress should choose a different function, since this model has none.

2-1/2 inch backset

The lockset has a 2-1/2 inch backset and a 1 by 7-1/8 inch front face plate, dimensions that must match the door prep exactly. Hardware is included for installation on steel gates or wood doors within the stated thickness range. Solid brass cylinder and two keys are supplied with the set.
