Air Insulated Caps for Metal Chimneys
1" Mesh for Outside California
This chimney cap is designed for air-insulated chimneys (double or triple wall). It has a tight, friction-fit which we recommend you also use with silicone to keep it in place.
Note: To get the correct size, measure the inside diameter of the center pipe. You must use the correct cap for each system. Using a single wall cap on an air-insulated
chimney can cause it to over heat.
