The i-CE Locking Systems Intumescent Self Adhesive Kit for Architectural Tubular Latch is designed to enhance the fire-resistance of door latch installations, suitable for 63/75mm latch sizes. This kit, rated for up to 60 minutes (FD60) for fire doors, includes self-adhesive intumescent pads that expand under heat exposure to maintain the integrity of the latch area. The pads come in a self-colour finish and are 2mm thick, suitable for providing a secure layer between the latch mechanism and the door material. The kit’s components appear to be dark grey or black, complementing a wide range of door finishes.
