The wheel on this caster has a non-marking thermoplastic rubber tread mounted on a polypropylene hub, and precision ball bearings that offer medium rolling resistance and quiet operation. The housing is made from high-grade nylon, with a square steel plate for mounting.
The wheel is nominally 100mm (4") in diameter, and the overall height of the caster is 136mm (5 3/8"). It has a 77mm × 67mm (3" × 2 5/8") steel plate attached to the caster by a ball-bearing swivel collar. It comes with a foot-operated brake that simultaneously locks the swivelling and rolling operations. Four 8mm (#14) screws required (not included). Weight capacity is 100kg (220 lb).
Made in Germany.
