Wheels and casters put equipment in motion: heavy-duty caster sets that make a server rack or equipment cabinet relocatable, replacement casters for carts and stands whose wheels have worn or seized, and the locking models that keep mobile equipment parked exactly where it was left. A rack that might ever move, and a cart that must never roll during use, both get solved here.
Casters are load-rated, mount-specific hardware: divide the loaded weight of the rack or cart across the casters with margin, and match the mounting - bolt pattern, stem size, or manufacturer-specific plate - to the equipment exactly, since rack casters in particular are usually family-specific. Choose wheel material for the floor: soft treads protect finished floors, hard wheels roll heavy loads on concrete. Locking casters are the default for anything carrying live equipment. COLAMCO supplies casters and mobility hardware for the racks, carts, and mounts business, government, and education facilities move.
