hjh OFFICE Spare Castor ROLO for Pin Diameter: 10 mm

The specially coated treads protect your high-quality hard floor from scratches and scuffs that conventional carpet casters can cause. Replacing the casters is quick and easy. The old casters can be simply pulled off with a little effort. Then just insert the new hard floor casters - done! The chair only rolls when under load. When you stand up, the casters brake to prevent unintentional rolling away. When loaded, the casters open and the chair rolls again. When choosing, please pay attention to the correct pin diameter and ideally use your old casters as a reference. For optimal measurement results, we recommend measuring the pin diameter of the old caster with calipers.
