Satin Chrome Mortise Lockset

The MAXTECH 1033BC-26DL is a heavy-duty mortise lockset finished in satin chrome. It uses a vestibule storeroom function where the latch is always locked from the outside and requires a key for entry. The unit is handed for left-hand doors and includes a solid brass cylinder supplied with two keys. It suits commercial or residential installations needing a durable, keyed-different locking solution.

Vestibule Function Constraints

This lock provides latch-only operation with no deadbolt or rocker mechanism. The outside lever remains rigid and cannot be unlocked by a thumb turn because none is present on the interior side. Entry is possible only by using a key in the external cylinder. The 2-1/2 inch backset and 1-1/16 by 7-5/8 inch face plate dimensions dictate the mortise pocket preparation required in the door.

Through-Bolted Installation Notes

Through-bolted knob plate assemblies and screwless knobs simplify alignment during fitting because the trim clamps directly through the door. Self-adjusting spindles accommodate minor variations in door thickness without manual setup. Installers must verify the left-hand orientation matches the door swing before cutting the mortise pocket. The solid brass cylinder should be lubricated periodically to maintain smooth key operation.

Questions about this item

Which handing and function should I select for a door that is locked from the outside with a key and has no inside thumb turn?

This model is a left-hand storeroom function: the outside cylinder operates the latch with a key, while the inside knob has no thumb turn and remains fixed.

What does the 2-1/2" backset mean when the lock is installed in the door?

The latch centre sits 2-1/2 inches from the door edge, so the mortise pocket must be cut to match that dimension.

How does the through-bolted plate assembly affect the lock's mounting?

Knob plates fasten with bolts that pass completely through the door, giving a rigid mechanical connection that resists levering.
