Type 03 T-rail suspension is convenient for frequent laundry, as it is quick and easy to remove and replace the ducts. The T-rail, so named because it looks like a T in the cross section, is made of anodized aluminum, making it an excellent choice for corrosive environments. The T-rail is fixed to a hard ceiling and the duct is then suspended from the rail. The duct will have sliders that slide down a channel in the Trail at the 12 o’clock position. The length of the duct straps that hold the sliders can be manufactured to specification. Type 03 suspension is available with All-In-One.
