Marks USA Series 2 Mortise Armored Deadlock

This mortise armored deadlock body fits standard door preparations and includes the #4035 strike in the box. The 2-1/2" backset matches common residential and light-commercial installations. A 1" bolt throw provides solid engagement with the strike plate. The satin chrome US26D finish resists wear in daily use.

Mortise installation limits and strike alignment

Mortise pockets must be cut to accept the 1-1/16" x 4-5/8" front dimensions of the stamped steel case. The included #4035 strike requires precise alignment with the 1" bolt throw for reliable latching. Wood or metal doors need sufficient thickness to house the full mortise body without weakening the stile. Retrofit projects may need chisel work to match the exact pocket size.

Check door thickness, handing and existing prep

Verify the door thickness accommodates the mortise case depth before ordering. Confirm the backset measurement on the door matches the 2-1/2" specification exactly. Ensure the door handing suits the lock orientation you require. Existing mortise pockets should be compared to the 1-1/16" x 4-5/8" front dimensions to avoid fitment issues.

Questions about this item

Is the 2-1/2" backset right for my door?

The 2-1/2" backset fits doors pre-drilled at that distance from the edge to the centre of the bore; measure your existing hole before ordering.

How far does the 1" bolt throw extend into the frame?

The bolt projects one inch when locked, giving a deep engagement with the supplied #4035 strike for solid resistance.

Will the 1-1/16" x 4-5/8" front plate match my mortise pocket?

That front dimension is the standard Series 2 mortise face size; check your pocket depth and width against those figures before installing.
