FabricAir Type 4

Type 4 T-rail suspension is especially great for larger diameter ducts that are frequently laundered, as it is easy to remove and replace the duct. The T-rail, so named because it looks like a T in the cross section, is made out of anodized aluminum, making it an excellent choice for corrosive environments. Two T-rails are fixed to a hard ceiling and the duct is then suspended from the rails. The duct will have sliders that slide down a channel in the T-rail at the 3 and 9 o'clock positions. The length of the duct straps that hold the sliders can be manufactured to specification.
