The Shepherd Hardware Elastic Blue Rubber Casters are designed with a super elastic rubber wheel that instantly regains its original form when a force is applied to the caster. As friction is considerably reduced, initial starting thrust required by user is brought to a minimum. The softness of this wheel will allow for easier rolling over obstacles, excellent rolling quality and noise reduction. These casters have fantastic abrasion resistance which increase their durability compared to standard rubber wheels.
