5498 - 5498 latch


Triple latching sets for use on steel fire resisting doors as specified by the Loss Prevention Council, which represents interested parties including the Department of Trade and Industry, Lloyds and the Fire Officers Committee.

The 5765 cylinder lockcase is available with single cylinder and thumbturn, or double cylinders as an option.

Supplied as standard without striking plate. Cylinder and accessories bolt through lockcase for added strength.

For finishes and dimensions see Lockcases Information appendix.

When ordering please specify hand, direction of door opening and door thickness.



Latchbolt is extended to 16mm to ensure 13mm engagement in the striking plate. Lever handles droop if the latchbolts are not fully engaged in the striking plate.

Each latchbolt follower is fitted with an additional arm incorporating a stub. The stubs protrude from the side of lockcases. When the three stubs are joined together with a steel bar (not supplied by ASSA ABLOY Security Solutions) inside the door, the latches can then be operated simultaneously with a single central lever handle.

Available with 50mm backset only.
