Key Override Deadlocking Bolt DB25KO

The Alpro DB25KO deadlocking bolt key override model offers the same functionality as the standard DB25 deadlocking bolt with provision for a europrofile cylinder as a means of mechanical override.  The ultra-slim design of the DB25KO enables fixing into very narrow sections. An advanced microprocessor module provides power reduction allowing continuous operation without heat generation as well as automatic voltage regulation, dual monitoring and access control features.

DB25KO key override deadlocking bolts offer a high physical security with a holding force of 1,000kg - automatic deadlocking and a bolt throw of 16mm.

Robust construction with all stainless steel bolt of 12.7mm diameter, linkages and springs. 3mm stainless steel faceplate and strike plates with fully enclosed mechanism.  Radius and square ended faceplates available.

Versatile installation designed to provide concealed high security locking on any single or double action, hinged or sliding door in timber or metal for vertical or horizontal mounting.
