17” x 21” Gelco Stainless Steel Chimney Cap – 13319

Description

Gelco Stainless Small-Mesh Chimney Cap 17 inch x 21 inch – Many localities (primarily in California) have spark arrestor codes that call for 1/2 inch spark arrestors. California code states that a sphere larger than 1/2 inch in diameter should not penetrate the screen. Thus, the spark arrestor screen actually measure 5/8 inch from center to center, but still won’t let a 1/2 inch sphere through. This makes them somewhat clog resistant while still meeting major code interpretations. Also, this cap offers the ability to fit square, round, rectangular, or oval flue tiles because of its special base. This is done by welding triangular pieces to the corners of the cap’s one-piece base. The Gelco Small Mesh Chimney Cap is a great choice when you need small mesh caps and/or a choice for different flue tile sizes and shapes.
