Designed for high cable volume conditions through fire-rated walls and floors while eliminating the burden of ongoing maintenance. The Series 44+ incorporates self-sealing intumescent pads that automatically adjust to the installed cable fill without the need for user manipulation. Under fire exposure, the intumescent pads expand and swell resisting the passage of smoke and flame.

The maintenance-free fire-rated 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 preventing the passage of smoke and flame.
