Rain/Chimney Caps and Dampers - Hy-C Black Metal Rain Cap
These rugged caps are electrostatically treated and finished with a high temperature paint for added corrosion resistance. Large openings in the spark screen mesh present less draft restriction than the smaller mesh common to other caps, optimizing draft and reducing the chance of creosote blockage. All models are completely assembled welded construction and all are “blowout proof.” The Combo model has metal tabs that distribute screw pressure to strong chimney tile corners. Secure installations with only 1" of exposed tile liner. (All caps are tab screw models but can be converted to slip-in caps by using the HY-C leg kit.)
Heavy 24 gauge single piece steel hood
16 gauge wire mesh (1/2" x 1 1/2" opening)
14 gauge steel base band
Black epoxy powder coated finish
24 gauge top
Chimney Cap Sizing Guide
Proper chimney cap sizing requires accurate measurement of both the inside and outside of the flue tile. There are no “standard” flue tiles. The size and wall thickness of chimney tiles are extremely varied, depending on the region and when a chimney was built. For this reason, accurate measurements (to the nearest 1/8") are imperative to correctly size a chimney cap. Estimates are not adequate.
Use these to install HY-C caps when the the flue tile is flush with the chimney crown. Loosely attach legs to each corner of the cap, then position the cap with the legs inside the flue. Finish by tightening the corner screws to secure.
