Split Sleeve Firestop System

Split Sleeve Firestop System

Our UNIQUE Split Sleeve Firestop System is a UL tested retrofit solution. It is designed for sleeving, firestopping and smoke sealing cables or wires already installed without a sleeve and in violation of the firewall rating. This zero-maintenance, through-penetration system is installed without any tools in minutes. No screws. No bolts & nuts. No clamps. No anchors. NO TOOLS REQUIRED. Saves time and labor. No need for installers to pull cables back out of the walls or floors after failing an inspection because the UNIQUE Fire Stop Split Sleeve design, a threaded, IMC conduit cut in half, can be fitted around existing cables.

This Split Multi-Cable Transit System is UL 1479 Classified for up to 4 hours. Made in the USA.

Our systems come with enough Unique putty for a minimum 25% and maximum 48% cable load.

Determine cable violation in firewall (how many violations), angle of entry or exit. Inspect violation to determine the proper Split Sleeve System size (1″, 2″, 4″ inside diameters). Up to 48% of the aggregate cross-sectional area of the Sleeve may be filled with cables in walls and floors rated up to 2 hours; 34% cable load for 4 hour ratings. See the Load Chart and Installation Pictorial.

‘Clean-up’ the firewall penetration (both sides of wall) ensuring not to nick the cable jacket(s). Use a slotted coupling to mark Sleeves hole size. Work the bottom half of the Split Sleeve under the cables as you insert it into the wall penetration. Support the cable(s) as the upper half of split sleeve is inserted through the firewall. Install top half, maintaining sleeve polarity. Look for machine or paint marks on end of the Split Sleeve halves to insure the halves are installed as machined.

Work cables through the slot of the 1st washer, work the washer over the sleeve halves and against the wall. (If your hole is not the size of the sleeve, apply a 3/8 bead of firestop caulk behind the first washer on each side of the wall.) Install the 2nd square washer for the first side and invert the slot so the slots in the washers are 180 degrees from each other. Work the cables through the slot in the first coupling and begin to screw it down the sleeve until equal lengths protrude on both sides wall.

Repeat the above procedure for the other side of the Sleeve system. Tighten the slotted couplings only enough to seat the square washers. Do not over- or under-tighten the slotted couplings. 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 bushing if there is a chance that more cables will be pulled in the future.

Be sure to fill out and adhere the Documentation Label as close as possible to the Sleeve System. Also, if you are installing several of these Sleeves, be sure to alphanumerically I. D. the walls. Use an indelible marker. Take a picture of your installed Sleeve System. You may need it in the future. Always refer to the UL document pertaining to your application for details and limitations!
