EZ-Path® EZD33FWS 33 Series Fire Barrier Pathway Kit, 10-1/2 in L x 3 in W x 3 in H, Square, 1 to 4 hr Fire Rating

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.
