EGS — Gripper Support

UL-listed as a support and firestop, the gripper support is strong enough to hold up to 30 feet of vent pipe. It installs very quickly and allows for adjustment of the pipe to wherever needed. A ring on the bottom provides the UL-required, one-inch clearance to combustibles (3" to 6" only; 7" to 10" are not UL-listed). No tools are required.
