hjh OFFICE Chair Caster ROLO ESD Hard Floor 11x50mm 5pcs.

These special castors are ideal for use in manufacturing, offices, or medical facilities. Any static charge that builds up can be dissipated by the conductive material in conjunction with suitable earthing measures. In addition, the specially coated treads protect your floors from scratches and marks that conventional castors can cause. Changing the chair castors is quick and easy. The old wheels can be simply pulled off with a little effort. Then, just insert the new castors - done! The chair only rolls when under load. When you stand up, the castors brake to prevent unwanted rolling away. When loaded, the castors open and the chair rolls again. When making your selection, please ensure you choose the correct pin diameter and ideally use your old castors as a guide. For an optimal measurement result, we recommend measuring the pin diameter of the old castor with a caliper gauge.
