MAXTECH Polished Brass Mortise Lockset

The MAXTECH Polished Brass Mortise Lockset is a left-hand storeroom lockset built for commercial doors. It operates with a vestibule function that keeps the outside lever always locked while the inside lever remains free. A cylinder on the outside and no thumb turn on the inside enforce key-only entry from the corridor side.

Replaces Marks Metro 116DW-X and 114DW-X

This lockset fits the same door preparation as Marks Metro 116DW-X and 114DW-X mortise locksets. The jump is worth it when a facility needs thru-bolted screwless lever plates with independent spring-loaded captivated spindles. Lever support springs add durability for high-traffic openings that demand ADA-compliant hardware.

Practical limits of mortise latch-only design

The latch-only configuration provides no deadbolt or rocker mechanism, so it cannot secure a door independently on the inside face. The wide face plate measures 1-1/4" x 8" with a 2-1/2" backset, which dictates the mortise pocket dimensions. Installers must verify the existing door prep matches these exact measurements before ordering.

Questions about this item

What size mortise pocket does the 1-1/4" x 8" face plate and 2-1/2" backset require?

The lockset fits a standard mortise pocket cut for a 1-1/4" wide by 8" tall face plate with a 2-1/2" backset measured from the door edge to the cylinder centre.

Which step is most often missed when fitting the thru-bolted screwless lever plates?

Installers often forget to engage the independent spring-loaded captivated spindles into the lever hubs before tightening the thru-bolts, causing the levers to bind.

When should the lever support springs and captivated spindles be inspected or replaced?

Inspect the lever support springs and captivated spindles during annual hardware maintenance; replace them if levers sag, fail to return sharply, or show excessive lateral play.
