Description
Suspension Rings in 400mm — galvanised steel hanging rings sized to support 400mm spiral ducting.
A suspension ring wraps the duct and provides a fixing point to hang it from the building structure, most commonly on threaded rod dropped from beam clamps or purlin clips. Rings hold the duct round and secure without crushing it, and spacing them at regular intervals keeps long runs straight and level. For larger diameters and heavier runs, see our two-piece split rings, which bolt together around the duct.
