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.
