Standard M6 bolts are typically used for fixing. The plate is zinc-plated pressed steel, providing a strong and corrosion-resistant mounting point.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pd-faq-item\"\u003e\n\u003cdiv class=\"pd-faq-q\"\u003eHow does the brake mechanism work on this swivel castor?\u003c\/div\u003e\n\u003cdiv class=\"pd-faq-a\"\u003eThe brake is a side-operated foot brake that engages directly onto the wheel to prevent rotation. When applied, it locks the castor in place, keeping equipment stationary on flat surfaces. It is released by pressing the opposite side of the brake lever. This type of brake is suitable for static positioning rather than heavy-duty braking applications.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pd-note\"\u003e* All dimensions are nominal and measured in millimetres unless otherwise stated.
