The BS Suspension ring M10 has a galvanised steel suspension ring with a M10 (10 mm) hole at both points of the segment.
The two separate segments have connection points (M10) at the ends where the suspension ring is screwed on. This is done by means of nuts M10 (10 mm, included), securing a threaded rod (M10 not included) through the 11 mm hole until the suspension ring sits snugly around the duct.
