Blake Uk13.5" ratchet bracket mitre stack strap is a device used in chimney construction to secure the chimney pipe to the roof and ensure that it is stable and safe. It is designed to be used with a metal chimney pipe that has a diameter of 8 inches or larger.
The strap consists of a ratchet bracket that is attached to the roof, a mitre that connects to the chimney pipe, and a stack strap that connects the ratchet bracket to the mitre. The ratchet bracket is adjustable, allowing it to be tightened securely to the roof surface. The mitre is designed to fit the shape of the chimney pipe, and the stack strap is used to secure the mitre to the ratchet bracket.
The 13.5" measurement refers to the length of the stack strap, which is the distance between the ratchet bracket and the mitre. This length may vary depending on the size and shape of the chimney pipe, as well as the height of the roof.
The use of a ratchet bracket mitre stack strap is important for chimney safety, as it helps to prevent the chimney pipe from becoming unstable or dislodged during high winds or other severe weather conditions. The strap should be installed by a qualified professional to ensure that it is secure and will provide adequate support for the chimney pipe.
