Codelocks CL250K-SS mechanical lockset stainless steel knob surveillance accessory

Mechanical push-button lockset with key override

The CL250K-SS is a stainless-steel knob lock that opens by a 13-button code or a standard SC1 key. It fits doors 1-3/8 in to 2-1/2 in thick and works on either hand without a separate cylinder change. The single user code suits a private office, a storage room or a residential entry where one credential is enough.

Zinc case with weather-resistant finish

The lock body is zinc alloy covered in a brushed stainless coating rated for outdoor exposure. A 2 3/4 in mortise latch and adjustable 2 3/8 in backset mount directly into standard door prep, so no extra drilling is required. The knob turns freely after code entry and relocks automatically when the door closes. Vandal-resistant construction protects the keypad from impact.

Includes code-change plug.

A code-change plug lets the owner update the combination in seconds without removing the lock from the door. The supplied paper template aligns the bore holes for a clean install, and the mortise latch is pre-assembled to the case. No batteries, wiring or software are involved, eliminating ongoing maintenance. Buyers who need multiple user codes, audit trails or remote management will need an electronic alternative.
