The white nylon wheel is best suited to smooth, hard floor surfaces such as concrete, tile, vinyl, laminate, and sealed timber. It is not recommended for deep-pile carpet or heavily textured outdoor surfaces, where a rubber or polyurethane wheel would be more appropriate. How does the brake mechanism work? The castor features an integrated foot-operated brake. Pressing the brake lever down with your foot locks the wheel in place, preventing rotation and swivel movement. Lifting the lever releases the brake and restores full mobility. No tools are required to operate it. How many castors do I need, and what is the combined load capacity? Most applications use a set of 4 castors. Each castor is rated to 65kg individually; however, the recommended maximum load for a set of 4 is 195kg ? calculated at 75% of the combined total to account for uneven weight distribution during movement. For loads approaching this limit, we recommend verifying the weight distribution of your specific application. What are the mounting hole dimensions, and how do I fit this castor? The top plate measures 60mm x 60mm with hole centres of 48mm x 38mm across 4 bolt holes. Fitting requires four appropriately sized bolts (not included) passed through the plate holes and secured into the base of your equipment. Ensure the mounting surface is flat and structurally sound to achieve the rated load capacity.
