Suspension type 13

Type 13 double H-rail suspension has great flexibility, making it ideal for high ceilings, larger diameter ducts and frequent laundry. The H-rail, named so because it looks like an H in the cross section, is made of anodized aluminum, making it an excellent choice for corrosive environments. Two H-rails are joined by an anodized aluminum semi-hoop that locks into the top of each rail. The semi-hoops are suspended using vertical cable drops. The duct is then suspended from the H-rails with sliders, in the 3 and 9 o’clock positions, that slide down the bottom channel of the H-rails. The length of the duct straps that hold the sliders can be manufactured to specification.
