Commercial Vestibule Mortise Lock

This heavy-duty mortise lockset is built for commercial and residential vestibule doors that must stay locked from the outside at all times. The storeroom function means the exterior knob is always rigid and requires a key for entry, while the interior knob provides free egress. It suits property managers and installers fitting high-traffic stairwell or corridor doors.

2-1/2 Inch Backset and Wide Face Plate

The lock carries a 2-1/2 inch backset and a wide face plate measuring 1-1/4 by 8 inches, which determines whether it fits the existing door preparation. Mortise pockets and edge bores must match these dimensions exactly, otherwise the chassis will not seat and the latch will not engage the strike.

Thru-Bolted Screwless Knobs Simplify Fitting

Through-bolted plate assemblies and screwless knobs with a self-adjusting spindle remove the need to align exposed screws during installation. The most common error is handing the lock incorrectly; this unit is left-hand only and cannot be reversed on site. Verify the door swing before cutting the mortise pocket.

Questions about this item

How does the 2-1/2" backset affect where I drill the door?

The 2-1/2" backset means the centre of the knob hole must be 2-1/2 inches from the door edge, so you mortise the lock body at that exact distance.

What does the wide 1-1/4" x 8" face plate require for installation?

The wide face plate needs a mortise pocket that matches 1-1/4 inches wide by 8 inches tall, and the through-bolted design anchors through the door thickness.

What does "Left Hand" mean for the knob orientation on my door?

Left Hand indicates the lock is built for a door that swings away from you with hinges on the left, so the outside knob and cylinder sit on the exterior side.
