💡 What makes dual wheel swivel casters better than single tires for rolling equipment?
A wider track layout balances floor contact across two points instead of one thin strip.
- Aluminum axle pins resist bending when you park loaded shelves on slight slopes
- Kept raceways trap factory oil so friction drops low even with concrete dust exposure
- Poly compound wraps stay flexible in cold shops while giving a handy pull force when you move heavy racks
