6" Class A Chimney Pipe 30 Degree Elbow Kit from Ultra-Temp This elbow kit contains two 30° elbows, two locking bands and one interior resupport. When creating an offset in the chimney pipe system, calculate the offset to determine the elbow angle. Locking bands are to be used at each joint. The interior resupport is designed to provide support above an offset where the upper elbow connects to the next pipe length. The elbows rotate 360° to provide the exact orientation required. The 30° Insulated Elbow in 5", 6", 7" and 8" sizes can be used for fixed offsets of 30° slope. Greater angles are prohibited by UL Standard 103 and by the terms of the product listing.
