The I-CE Locking Systems Intumescent Self Adhesive Kit is designed for enhancing fire resistance in door locking mechanisms, specifically for a 3L Deadlock. The contents are self-adhesive, simplifying the installation process by providing an easy-to-apply method and securing the kit components to the appropriate areas on the door and frame. The intumescent material expands when exposed to high temperatures, helping to maintain the integrity of the door assembly during a fire. This particular set is suitable for use with 63/75mm deadlocks and is 1mm thick, indicating it is likely meant for FD30 fire-rated doors, which offer at least 30 minutes of fire protection. The self-color finish on each component looks homogenous and serves to blend with a variety of door finishes.
