Expanders
Expander fittings for swivel castors
Swivel castors with a "fixing hole" or "bolt hole fitting" can be supplied with expanders for mounting in round tube or square tube. An expander fitting consists of a long Allen screw - usually M10 x 30 mm, M10 x 80 mm or M12 x 80 mm), complete with lower and upper cone and rubber or plastic expander.
Mechanism: by tightening the Allen bolt under the fork swivel head, the expander expands and clamps into the tube/sleeve. The specified size must match the inner size of the tube/sleeve.
