What is the diameter of the opening in CPF-77921? I have a chimney pipe with an outside diameter of 10 inches. Is this product the right size for this pipe ?

This pitched-ceiling plate is designed for MetalBest chimney pipes with a 8" outer diameter. However, they also make one that is suitable for a chimney pipe with a 10" outer diameter: MetalBest Ultra-Temp 8 Inch Diameter Chimney Pipe Pitched Ceiling Plate - Adjustable
The "8-Inch" referred to in that item title is the inner-diameter of the pipe, so a pipe with a 10" outer diameter would work with that pitched-ceiling plate.

Can I use this MetalBest Ultra-Temp 6 inch diameter chimney pipe pitched ceiling plate on the wall so my pipe goes through the wall at a 45 degree angle?

Answer:This collar should only be used around Class A pipe that is passing through a ceiling at up to a 30 degree angle or through a wall at a perfect horizontal. Class A is not designed to angle at a 45 degree through a wall, as flow will stagnate and build up of creosote can result.
