Split Sleeve Installation Pictorial

Split Sleeve Firestop System

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.
Clean-up the firewall penetration (both sides of wall) ensuring not to nick the cable jacket(s). Use one of the washers as your guide.
Use one of the SSS halves to protect your cables. After you clean up the hole, slide the bottom half of the threaded sleeve under the cables. Take care to protect your 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. NOTE that the inside washers for both sides does not have printed information. The SSS will need a bead of caulk if the holes in the wall are not exactly the OD (outside diameter) of the SSS to be installed.
Install the second slotted washer, inverting the slots 180 degrees from each other (12 o’clock). Make sure UL label is facing out! Position sleeve protrusion equally.
Work the cables through the slotted coupling and screw it down against the washers. HAND TIGHTEN ONLY.
Repeat this procedure on the other side of the wall. HAND TIGHTEN ONLY.
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 sealing Systems up to 4 hours. UNIQUE 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. There are a pair of zip ties for securing the split bushings in place after installation.
Install the documentation labels on both sides. We advise you to ID (indelible marker) and take a picture of your installed system for an added bonus – protection of your workmanship.
