Specified Technologies Inc. (STI) EZDP33FWS 3 x 3 x 10.5 Inch Fire Rated Pathway Kit

The EZ Path Series 33 Fire-Rated Pathway is a maintenance-free pathway solution for moderate cable volumes through fire-rated walls and floors. The Series 33 incorporates built-in intumescent pads that automatically adjust to cable fills. When exposed to flame and high temperatures, the intumescent pads expand to form a dense insulative char that prevent the passage of smoke and flame.
