Smooth Penetrator Firestop Sleeve

Cable Load Chart/Pricing   Installation Pictorial   Assembly Instructions   Drawings   UL Systems


The Smooth Penetrator firestop is used in new horizontal cable installations for walls rated up to 2 hours. No caulk is required between the sleeve and the wall. Our most economical product, it makes firewall penetrations neat, clean, and efficient. This design allows for cables to be pulled through the firewall without any "attendance", even at a 45 degree angle. The sleeve acts like a roller in the wall while cables are being pulled. A real time saver!
Intumescent putty is included. Fire stopped and smoke sealed 100% of the time.

See the Cable Load Chart for specifications.
