Mortise locks for tubular frame doors

Our mortise locks for tubular frame doors are specially developed for the requirements of narrow door profiles made of aluminium or plastic. Thanks to their compact design, small backset dimensions and reversible latch, they are ideal for installation in single and double-leaf tubular frame doors – both in new buildings and for retrofitting.

With robust mechanics, tested quality according to DIN 18251 and series such as Series 13 and 18, BKS mortise locks offer reliable protection for doors with high traffic. The locks can be combined with profile cylinders and fittings; a free-running cylinder is not required.
