DuraVent Model BV Gas Vent Support Collar and Hardware: the support band without a plate
The DuraVent Model BV Gas Vent Support Collar and Hardware is a clamping band that transfers the pipe’s weight to a support plate. The plate is not included. This is the band to choose when your installer makes a plate on site or needs one for an opening that is an unusual size. Tabs and short screws secure the band around the pipe, and the band rests on the plate. 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.
Choose a 3, 4, 5, or 6 inch diameter to match your vent pipe. A support near the bottom of a vertical run carries the vent’s weight. The pipe sections connect with DuraVent’s DuraLock joint: the ends push together until seated, then a thumb press on the DuraTab secures the connection in place of a screw. Need the plate too? See the DuraVent Model BV Support Assembly, the band and plate together. The DuraVent Model BV Gas Vent Support Collar and Hardware ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
