Polished Brass Mortise Lockset

The MAXTECH LKMT1033AX3L is a heavy-duty mortise entry lockset finished in polished brass. It features a wide face plate measuring 1-1/4" x 8" and solid brass surface-mounted plates. The set includes screw-on knobs with a swivel spindle and a solid brass cylinder supplied with two keys.

Left Hand Door Applications

This lockset suits left-hand doors requiring a 2-1/2" backset and a 1" deadbolt throw. It provides a cylinder on the exterior and a thumb turn on the interior for entry function. Buyers needing a right-hand configuration or a different backset dimension should look at alternative models.

Surface Mounted Installation

Installation uses surface-mounted hardware with screw-on knobs and a swivel spindle assembly. The wide face plate requires accurate mortise preparation in the door edge. Misalignment of the spindle or cylinder during fitting commonly causes binding or latch malfunction.

Questions about this item

What door preparation is required for the 1-1/4" x 8" wide face plate?

The mortise pocket must accept a front plate measuring 1-1/4 inches wide by 8 inches tall with a 2-1/2 inch backset and 1 inch deadbolt throw.

Can the solid brass cylinder be rekeyed to match an existing Marks 91A/3-X keyway?

The cylinder uses the same keyway as the Marks 91A/3-X reference, so a locksmith can rekey it to your existing keys.

How do I confirm the left-hand orientation is correct after installation?

With the door closed, the knobs should be on the left side when viewed from the outside and the thumb turn operates the deadbolt from the inside.
