What is 5/8″ Small Mesh for Spark Arrestor California Chimney Caps?
Since these spark arrestors are primarily used in California and Oregon, they are called California Chimney Caps.
for round flues: 10″ diameter, 12″ diameter, 14″ diameter, 16″ diameter, and 18″ diameter.
The 5/8 inch mesh stainless steel chimney cap above is available in the following sizes to fit square, rectangular or oval flues: 8″ x 8″, 8″ x 13″, 8″ x 17″, 10″ x 17″, 13″ x 13″, 13″ x 17″, 13″ x 21″, 17″ x 17″ and 17″ x 21″.
According to the National Fire Protection Association, chimney caps with 5/8″ mesh will not allow a 1/2″ sphere through them, and thus are considered the industry standard for California chimney caps. The chimney caps above all have this specially sized mesh to conform to these spark arrestor codes.
In addition, you often find round, oval, and large rectangular flue tiles sizes in California, Arizona, Nevada, and Oregon. Many spark arrestor chimney caps above have a special base that fits either the square and round flue tiles or the rectangular and oval flue tile sizes.
Oval flues can have straight sides and rounded ends like a racetrack, or curved sides and ends. (Flues with straight sides and ends, with rounded corners are actually rectangular flues.) Only chimney caps designed specifically for oval flues will fit them correctly.
Do you have cedar shingles on your roof, home, or nearby buildings? If so, you should certainly consider California spark arrestor chimney caps with small, 5/8 inch mesh.
Even if your locality does not require 5/8 screening or California spark arrestor chimney caps, if you have an oval flue tile, these are the appropriate chimney caps for your flue.
