What this lock is and who it fits

The MAXTECH LKMT1033B-26DL is a satin chrome mortise entry lockset built for heavy-duty commercial and residential doors. It suits specifiers and installers who need a Grade 1 style platform with through-bolted trim and a left-hand swing. The brass construction and solid plates support high-traffic entrances where durability and a clean 26D finish are specified.

The spec that decides fit

The 2-1/2 inch backset and dedicated left-hand mortise chassis are the single dimensions that determine whether this lock will align with the door preparation. Through-bolted knob plates and self-adjusting spindles simplify installation on standard mortise pockets, but the handing cannot be reversed in the field. Verify the backset and swing direction before ordering.

Behaviour under sustained use

Through-bolted assemblies and screwless knobs resist loosening when the door cycles repeatedly through the day. The solid brass cylinder and heavy-duty springs maintain consistent latch retraction and deadbolt throw over extended operation. Solid plates distribute torque across the door face, reducing wear on the mortise pocket during continuous commercial traffic.

Questions about this item

How does the 2-1/2" backset position the lock in a standard door?

The 2-1/2" backset places the cylinder centre 2-1/2 inches from the door edge, matching the common commercial mortise preparation.

What does the "Like Marks 114A/26D" series reference tell me about cylinder compatibility?

It indicates the lock follows the Marks 114A pattern, so standard 1-1/8" mortise cylinders with the same cam will fit the 26D satin chrome housing.

What door thickness and prep does the through-bolted, screwless knob assembly require?

Through-bolts pass through the door and lock case, so the door must be drilled for the spindle and two bolt holes; the self-adjusting spindles accommodate typical 1-3/4" to 2" thick doors.
