Set of 5 stiff-roll castors for industrial chair

The castors make your workshop or office chair mobile so that you can easily move it between workstations. They have a diameter of 50 mm and each castor has a stem for insertion into a hole in the base of the chair. Stiff-roll castors are suitable for chairs with a high seat height as they prevent the chair rolling when you sit down. The castors are sold in a pack of 5.
