When you need to install a cable outlet inside a firewall or smoke wall, our Membrane Firestop Cable Sleeve is uniquely qualified for the job. Our “angled design” allows a BUNDLE of cables to be dropped inside a Firewall Membrane. This is the ONLY mechanical multi-cable system available that performs like this while maintaining proper bend radius specs.
This UNIQUE product is an angled firestop cable sleeve that cuts its own hole and installs in 2 minutes, allowing for a UL Classified path to fish cables inside a firewall. The System creates its own hole with the sharp point on the back side of the sleeve. A bead of caulk (not included) is applied to the back of the system and the sleeve is secured to the wall with expanding anchors. UNIQUE Intumescent Putty for sealing this firestopping system is included.
We make this system in the USA in our own factory. UL classified for fire-rated gypsum board/stud walls (one side) for up to 2 hours.
Available in 1″ and 2″ diameters.
