Fire resistant INTU FR COLLAR L SLIM is a universal pipe collar with a height of 30mm, consisting of an external stainless steel casing and an intumescent insert made of graphite based components, with an adhesive tape. Under the high temperature (about 140 ?C), the insert expands and closes the opening, preventing the spread of fire. Steel casing of the collar has mounting brackets (segments). In order to obtain the desired diameter of the collar, the segments can be easily separated.
