SELKIRK Sure-Temp 30 deg. Insulated Elbow Kit includes two 30 degree elbows, two locking bands, and one interior re-support, designed to allow the chimney to be offset to avoid obstructions before exiting the roof. This kit complies with UL standard 103, which prohibits angles greater than 30 degrees, ensuring safe and reliable installation. The interior re-support provides a secure attachment of the chimney to interior joists or framework, while the locking bands enable 360-degree rotation and securely lock the components in place at the exact offset needed. These insulated elbows maintain the same two-inch air space as chimney sections and are made of durable stainless steel. Available for 6" and 8" pipe sizes, they are compatible with the Model SSII chimney system, making them a practical and efficient solution for chimney installations. Model Number: 206211
