(IMC) Intermediate Metal Conduit.

The system includes:

1 – 12″ threaded IMC sleeve

2 – large flat washers

2 – threaded couplings

2 – documentation/warning labels

1 – A package of UNIQUE Intumescent Putty

Threaded Firestop Sleeves come in

INSTALLATION PICTORIAL

A 4 inch System will require a 4 & 1/2 inch hole

minimum! Most people should drill a 5 inch

hole for the 4 inch Threaded Sleeve.

Pre-drill the hole in

advance. BE SURE to

drill the hole to the

outside diameter

(O.D.) of the System

you will be using.

Remove the documentation warning label.

Disassemble one side of the System.

Adjust the

coupling, washer

and bushing so

that the sleeve will

protrude evenly on

both sides when

installed.

Feed the System into the hole you have pre-

drilled. Go below and install the other half of

the hardware.

The vertical

application of the

Threaded Sleeve

requires the sleeve

to be packed (3 inch

depth) with mineral

wool batt insulation.

This keeps gravity from having any effect on

the intumescent putty.

If used horizontally, this system needs

no wool batt.

When the cables

reach their

destination, install a

minimum 1/2 inch

thickness of Unique

Putty per the vertical

application.

This System used horizontally, needs a

minimum 1 inch thickness of putty.

Fill out and attach the documentation/warning

label.

Don’t forget to take a

picture of your completed

installation for future

reference.
