The Membrane Penetrator
What if the cable outlet is required to be installed inside of the fire wall or smoke wall? We have a Sleeve System that will do the job. This device installs in 2 minutes and offers a U. L. Classified, clear and sealed path to "fish" cables inside a fire wall. At a 40 % Cable Load, you may install up to (9) Cat 5 UTP cables in it on the MP-1.

See U.L. System#W-L-3230. It may be used in a 1 or 2 hour rated drywall.

The System creates its own hole and is secured with expanding anchors. There are a pair of anchors for 5/8 inch drywall. Intumescent putty for this system is included as well.

Make sure plate fits flush against the wall. Now, remove the plate and go on to the next step.

(Be sure to clean out the back of the wall where the hole was made by the sleeve.)

Apply a small bead of (non intumescent) firestop caulk to the back of the plate and around the sleeve to seal the Membrane Penetrator to the wall. 

Re-insert the system in to the hole you made.

There are small slots in the holes for the anchor to grab, allowing you to fully expand the anchor while securing the plate flush to the wall. 

Note: The Membrane Penetrator is now permanently installed. Don't forget to carefully push the bushing back on. Drop your cables through the sleeve and down to the wall outlet.
