13" x 21" HomeSaver Stainless Steel Single-Flue Chimney Cap, 5/8" Mesh, 304-Alloy

HomeSaver Stainless Small-Mesh Chimney Cap 13" x 21" - Many localities (primarily in California) have spark arrestor codes that call for 1/2" spark arrestors. California code states that a sphere larger than 1/2" in diameter should not penetrate the screen. Thus, the spark arrestor screen actually measure 5/8" from center to center, but still won't let a 1/2" 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 HomeSaver 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.
