Expandable metal sockets for round or square tubes.
Made from hinged parts whose shape adapts to the inner walls of the tube.
Tightening of the screws on two opposing metal cones exerts pressure inside the tube. The serrated shape of thesupport faces on the tube and the top cover of the castor prevent accidental loosening.
Applications: castors with an eyelet of 12 mm, institutional castors, etc.
Minimum thickness of tube required: 1.5 mm.
