Move rack cabinets with more control using StarTech RKCASTER2 heavy-duty casters. This 4-pack is built for server racks, cabinets, and 4-post racks that need repositioning during deployment, maintenance, or floor planning. The caster set supports a stationary load up to 550 lbs and a rolling load up to 165 lbs, giving teams a practical way to relocate equipment while keeping the rack stable when parked. Each kit includes universal 2-inch swivel casters and the mounting hardware needed for installation: 18 M6 screws, 18 M6 nuts, and 18 washers. The casters are designed for racks with a 45 mm x 75 mm bolt pattern, which makes them a fit for many common rack configurations. For teams managing dense equipment layouts, the ability to roll a cabinet into position can save time during staging, cable work, and room reconfiguration. Built with cold-rolled steel and plastic, this caster kit is a straightforward upgrade for racks that need mobility without moving to a dedicated cart or enclosure solution. It is a practical choice when the rack itself must remain the deployment platform.
