Fitted with a grey rubber-tyred polypropylene wheel and housed in a zinc-plated pressed steel swivel head, it is designed for smooth, quiet rolling across hard and semi-smooth floor surfaces. The integrated directional brake locks the wheel firmly in place at the press of a foot, making it well suited to retail display units, exhibition stands, mobile workshop trolleys, and light furniture that needs to stay put when stationary. With a 4-hole top plate for straightforward bolt-on installation and a 50kg per-castor load rating, this unit delivers dependable everyday performance in commercial and light industrial settings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background-color: #fffbd3;
