INSTALLATION PICTORIAL

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).

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 washer’s 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 the “split bushings”, taking care not to

open the bushing any more than is needed to

get the cables in.

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 documentation labels provided

with the system and take a picture of your

installed system.
