Split Sleeve: Installation Pictorial

 

System contents:
(2) 12 inch long threaded 1/2 sleeves, (4) slotted washers, (2) slotted couplings, (2) split bushings, a documentation/warning label, and a package of Unique Putty.
A common penetration violation in a sheetrock 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.
Slide the top half over the cables, maintaining sleeve polarity, until both halves protrude evenly.
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 min. inch thickness of the supplied intumescent fire stop putty in both ends of the Sleeve System.

See our U.L. Systems page 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 label provided with the system and take a picture of your installed system.

NOW, BRING ON THE INSPECTOR!

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software
