Why choose it

Built for the demands of data centers, these casters combine strength, durability, and safety. The polyurethane wheels protect sensitive flooring from scratches and reduce vibration, while the total lock brakes ensure the rack stays exactly where you need it during installation or servicing. The galvanized steel housing resists rust, making them suitable for long-term use in various environments. With a low-profile design, they add minimal height to your rack, preserving clearance in tight spaces.

Ideal use cases

• Moving server racks and network cabinets within data centers or server rooms
• Retrofitting existing racks with mobility for easier access to rear panels
• Supporting heavy equipment in workshops, labs, or industrial settings
• Creating mobile workstations or equipment carts from rack enclosures

Good to know

Installation is straightforward with the included screws and washers, and the top plate design fits standard rack base mounting patterns. The casters are compatible with concrete, tile, and carpeted floors, making them versatile for different facilities. Always engage the total lock brakes when the rack is in its final position to prevent unintended movement.
