The multi-purpose Aero Foil cap is comparable to the Zipp Air (Zippy Caps) caps previously made by Breidert and the Gary 1092 Caps made by Gary Metals. The heavy duty galvanized steel construction is 26 gauge American steel and the cap is ideal for horizontal or vertical termination or air makeup applications. The design is intended to prevent wind induced air pressure variations and keep rain out. American made with pride, quantity and wholesale pricing available upon request.
