One-piece suspension rings are designed for installation of round spiral ducts and plain round ducts. The lugs at the top of the suspension ring top are tied together with a steel bolt and a matching nut.
The suspension ring's form enhances the stiffness of the ductwork clamped within and provides an easy way of fastening the suspension ring to steel structures. Suspension rings are also an ideal solution for ducts insulated after their suspension, because they can be fully covered by aluminium foil-clad or rubber insulation.
