Type 5 is an elegantly fixed all-aluminum suspension method. The H-rail, so named because it looks like a H in the cross section, is made out of anodized aluminum, making it an excellent choice for corrosive environments. The H-rail is hung using field adjustable anodized aluminum rods that lock into the top channel of the rail. The duct is then suspended from the rail. The duct will have sliders at the 12 o'clock position that slide down the bottom channel in the H-rail. The length of the duct straps that hold the sliders can be manufactured to specification.
Type 5 suspension is available with All-In-One.
