MightyVent 4″ UL Elbow Strap

$95.00

The MightyVent AF 4″ elbow strap supports an offset in your MightyVent 4″ chimney. Its 304 stainless band bolts around the top elbow, and the two long arms fasten to an adjacent joist or rafter. One strap comes with each MightyVent 4″ 30° elbow set; add this one when two pipe sections sit between the elbows, or as a replacement.

*** Limited Availability: Initial stock of the new UL parts line is limited, so it’s currently only available if you’re purchasing a Dwarf Stove. Use another brand of stove with 4″ pipe? Let us know, and we’ll follow up when more is available. Already purchased a Dwarf Stove and need parts? Contact us and we’ll help you get set up. ***

What an elbow strap does

In an offset, the elbows and the pipe between them sit at an angle, and their weight pulls on the joints. The strap’s band goes around the top elbow and its arms fasten to the framing, so the offset is supported before more pipe goes on above. If two pipe sections sit between the elbows, a second strap goes around the joint between them.
