Product Details:
Rock-Vent Class A Chimney Pipe Elbow Kits are available in 15 and 30 degree options. Each elbow kit includes 2 elbows and 1 elbow support. Elbows are used to offset obstructions such as framing joists in your installation. The elbow support is required between two elbows to support the chimney weight created by the offset. The two straps of the support are 36 inches in length. It's not recommended to use more than 4 elbows on an installation.
We offer three steel options for Elbow Kits: 304L Stainless Steel Inner/Galvalume Outer, 304L Stainless Steel Inner/430 Stainless Steel Outer, or 316L Stainless Steel Inner/430 Stainless Steel Outer.
The length of the chimney pipe can be no greater than 72 inches and no more than 2 sections of chimney pipe can be installed between the offset elbows. A second elbow strap is required when two chimney sections are used in the offset (available as an optional accessory).
