Description

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.
