DuraVent Model BV 45 and 60 Degree Adjustable Elbow: a sideways step around framing
The DuraVent Model BV 45 and 60 Degree Adjustable Elbow is a bend for routing a gas vent around framing. Used together, two elbows move the pipe sideways past a rafter, joist, or beam, then point it upward again. Its three sections adjust to 45 or 60 degrees, and the base turns a full circle to line up the bend. 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 Model BV pipe. The sideways step needs support both above and below it. Any sideways stretch also needs support every 5 feet. The DuraLock connection joins with a push until the ends seat. Press the DuraTab down with your thumb to secure it in place of a screw. Need a square turn instead? See the DuraVent Model BV 90 Degree Adjustable Elbow. The DuraVent Model BV 45 and 60 Degree Adjustable Elbow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
