<p>A glide castor comprises a two-part body assembly consisting of lower and upper mouldings fitted together. The lower moulding has a convex bottom ground-engaging surface and an integral upstanding boss with a bore for a mounting spindle. The upper moulding is of cap-like form and seats on a peripheral seating on the lower moulding. An integral inwardly projecting lip of the upper moulding provides snap-on engagement with said boss, thereby to hold the two mouldings together as an assembly.</p> |
