Split Sleeve Retrofit Fire Stop Firestop

Split Sleeve Retrofit Fire Stop Firestop

The Split Sleeve System™ is a UL Classified retrofit solution designed for sleeving cables which have already been installed without a sleeve and are in violation of the firewall. Installers do not have to pull cable back out of the walls or floors after failing an inspection because of the unique Split Sleeve System design (a threaded, rigid conduit cut in half) which can be fitted around existing, installed cables.

Systems are available in 1, 2, & 4 inch diameters. Part #'s are: SSS-1 for the 1" diameter, SSS-2 for 2", and SSS-4 for 4".

Pictorial Installation Process

	System contents: (2) 12 inch long threaded 1/2 sleeves, (4) slotted washers, (2) slotted couplings, (2) split bushings, 2 documentation/warning labels, and a package of UNIQUE Intumescent Putty.  The zip ties are for the split bushings.
	A common penetration violation in a sheet rock firewall. A Sleeve will control and direct the expansion of the fire-rated intumescent putty. Without a sleeve, this penetration may fail to restore the hourly rating of this wall.
	After you clean up the hole, slide the bottom half of the threaded sleeve under the cables.  Look for the machine holes near the ends of the sleeve halves to maintain polarity.
	Slide the top half over the cables, maintaining sleeve polarity, until both halves protrude evenly.  Position the sleeve with the seams at 9 and 3 o’clock.
	Work the cables through the slot in the first washer and work the washer down the sleeve, against the wall. The first washers slot should be positioned at the 6 o’clock position.
	Install the second slotted washer, inverting the slots 180 degrees from each other (12 o’clock).
	Work the slotted coupling around the cables (again, maintaining polarity) and screw it down against the washers. The coupling should be hand tightened only. Repeat this procedure on the other side of the wall.
	Install a minimum 1-inch thickness of the supplied UNIQUE intumescent firestop putty in both ends of the Sleeve System. See our UL Systems documentation for Systems rated up to 4 hours. Intumescent putty is supplied with the system.
	Install the “split bushings”, taking care not to open the bushing any more than is needed to get the cables in.
	Install the documentation labels provided with the system and take a picture of your installed system. NOW BRING ON THE INSPECTOR!
