The I-CE Locking Systems Intumescent Self Adhesive Kit for 5L Dead/Euro lock 63/75mm 1mm (FD30) is designed to enhance the fire resistance of a locking mechanism on doors, particularly those rated for 30 minutes of fire resistance (FD30). This kit includes a set of intumescent strips that are self-adhesive for easy application onto the lock and door hardware. The components in the kit appear to be of a self-color finish, which typically indicates a natural or untreated state of the material. The intumescent materials expand in the presence of high temperatures to seal any gaps and prevent the passage of smoke and fire. This particular kit is suitable for both 63mm and 75mm 5 lever deadlocks or Euro profile locks. Its simplicity and efficiency make it a crucial part of fire safety measures for both residential and commercial properties.
