Specified Technologies Series 22 Fire Rated Pathway Kit (with device, wall plates & labels)

Reference#: 72784
Item#: EZD22


The EZD22 EZ Path® Series 22 Fire Rated Pathway is a pathway device designed to allow cables to penetrate fire-rated walls without the need for firestopping. This device features a built-in fire sealing system that automatically adjusts to the amount of cables installed. Once installed in a fire barrier, cables can be easily added or removed at any time without the need to remove or reinstall firestopping materials.

The EZD22 EZ Path® Series 22 Fire Rated Pathway consists of an enclosed heavy gauge galvanized steel pathway lined with intumescent material engineered for rapid expansion when exposed to fire or high temperatures, quickly sealing the pathway and preventing the passage of flames and smoke.

EZ Path® Series 22 Fire Rated Pathway is painted safety orange for easy identification. Its compact square profile allows a maximum number of cables to be installed in a relatively small area. The pathway measures approximately 1-1/2” x 1-1/2” (37mm) and is 10-1/2” (267 mm) long.

EZ Path® Series 22 Fire Rated Pathway is designed for easy installation in walls. Tested and approved cable capacities range from 0 to 100% visual fill. EZ Path® Series 22 Fire Rated Pathway when installed with provided wall plates is designed for new cable installations. In these installations, the device does not require mechanical attachment to either the wall or the wall framing and may be installed after the w allboard has been installed. EZ Path® Series 22's split body design also allows the device to be easily disassembled and installed around previously installed cables in existing construction.

EZ Path® Series 22 Fire Rated Pathway provides exceptional cable capacity. A single unit installed in a wall has an equal cable carrying capacity of a 2” (50 mm) diam sleeve utilizing typical putty firestop systems (35% cable loading).

EZ Path® Series 22 Fire Rated Pathway is UL Tested and Classified in accordance with ASTM E814 (UL1479). Systems are available for common wall construction with ratings up to and including 2 hours.

All data, video, and communications cable bundles shall utilize an enclosed fire-rated pathway device wherever said cables penetrate rated walls. The fire-rated pathway shall contain a built-in fire sealing system sufficient to maintain the hourly fire rating of the barrier being penetrated. The self contained sealing system shall automatically adjust to the installed cable loading and shall permit cables to be installed, removed, or retrofitted without the need to remove or reinstall firestop materials. The pathway shall be UL Classified and tested to the requirements of ASTM E814 (UL1479).

No maintenance of the pathway is normally required. The interior of the device should be inspected before and after any modifications to the cable bundle. If any damage to the intumescent pads lining the top and bottom of the pathway is found, contact the factory to obtain replacements.

The use of this device is subject to local, regional and national codes. Consult the local Building Code Official or Authority Having Jurisdiction regarding any regional or local requirements that might influence the selection or use of this product.
