40-foot roll (12.2 m) of intumescent firestop wrap. Flexible wrap makes installation easy.
Simply roll out and cut as much material as required to wrap around the penetrant. Works with most non-metallic and metallic insulated penetrants. Used for “in-hole” firestop installations or in conjunction with 3M™ Fire Barrier RC-1 Restricting Collars. When the wrap is installed “in-hole” in conjunction with a 3M™ Fire Barrier Sealant or Moldable Putty+, it also provides a cold smoke seal, which helps prevent the spread of toxic gases and other combustion by-products even before heat initiates the intumescent process. Available in 2 in. x 40 ft. roll (50.8 mm x 12.2 m).
