Compact GearBoss® SportCarts™ can be used as part of a larger GearBoss installation or as a mobile, stand-alone solution. They are designed for use in small spaces and for sports that require less storage. Four heavy-duty, 5" (127mm) swivel casters make mobility a snap. The nimble SportCart will navigate narrow hallways, shorter door openings and most elevators. It's the small-space storage solution.
