MAXTECH LKMT1033BX-26DL Mortise Entry Door Lock

Mortise Entry Lockset

The MAXTECH LKMT1033BX-26DL is a heavy-duty mortise entry lockset designed for commercial and residential doors requiring robust security. It features a satin chrome 26D finish on solid brass components with a wide face plate measuring 1-1/4" x 8". The left-hand configuration includes through-bolted knob plate assemblies and self-adjusting spindles with screwless knobs. A solid brass cylinder and two keys complete the entrance function set.

Durability and Operation

Solid brass construction provides inherent corrosion resistance and structural rigidity for high-traffic environments. Through-bolted plate assemblies distribute mechanical stress across the door thickness, reducing wear on mounting points over time. Screwless knob design eliminates exposed fasteners that can loosen with repeated cycling. The self-adjusting spindle accommodates minor door alignment shifts without binding or excessive friction.

Replacement and Upgrade Fit

This lockset replaces existing mortise bodies with a 2-1/2" backset and 1" deadbolt throw where a wider 1-1/4" x 8" face plate covers previous cutouts. The Marks 114A/26D-X like footprint allows direct retrofit in many commercial door preparations without new mortising. The jump is worth it when the current hardware shows latch bolt wear, loose trim, or finish degradation that compromises security or appearance. Buyers needing right-hand operation or a narrower face plate should verify compatibility before purchase.
