✅ Premium Grey Elastic Tread

The outer wheel surface is made of special elastic material with multi-ring anti-slip texture. It delivers smooth, quiet rolling on concrete, epoxy and tiled floors. It will not leave black marks on the ground, effectively protecting airport floor surfaces. Outstanding abrasion resistance ensures long service life under frequent continuous operation.
