DuraVent Model BV Wall Band: a strap that steadies the vent without carrying its weight
The DuraVent Model BV Wall Band is a strap that holds a vertical gas vent steady beside a wall. It clamps around the pipe and fastens to the wall with four wood screws to keep the run from swaying. Place it just above the T shaped tee fitting, then every 6 feet up the run. This band does not carry the pipe’s weight. Choose a 3, 4, or 5 inch size on this page to match your vent diameter. Model BV is DuraVent’s Type B gas vent, the double wall pipe that carries the exhaust from a gas furnace, boiler, or water heater out of the house.
A separate support near the bottom carries a vertical run. The vent also needs a firestop to close the opening at each floor or ceiling it passes through, plus an attic shield to keep insulation away in an attic. A sideways run needs support every 5 feet. Need a band that carries weight too? See the DuraVent Model BV Wall Support and Band Assembly, a support for 35 feet of vent. The DuraVent Model BV Wall Band ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
