Wheel Type:
Hard Rubber Wheels will protect your equipment or cart. Hard Rubber Wheels are easy to roll, quiet, and great for smooth concrete floors, wood, tile, linoleum, carpet, and most floor types. Hard Rubber Wheels are resistant to chemicals, mild acids, oils, and water. Hard Rubber Wheels could leave streaks on the floor IF the wheel cannot roll or swivel. If the caster and wheel can swivel and maneuver, you should not worry about the wheel leaving streaks.
