Caster Kit for 42U Open Frame Rack

This set of four heavy-duty casters attaches to the base of the 42U Adjustable 4 Post Open Server Equipment Rack. It provides mobility so the rack can be repositioned within a server room or data centre. The kit is designed specifically for the 4POSTRACKBK model. Installers who need a stationary rack will not use this accessory.

Mobility Under Full Equipment Load

The casters are built to support the weight of a fully populated 42U rack during relocation. They allow the cabinet to be rolled into position and then levelled without unloading mounted servers or network gear. This reduces downtime when rearranging floor layouts or accessing rear cabling.

Upgrade from Fixed Feet or Lower-Capacity Racks

The kit replaces the standard fixed feet on the 4POSTRACKBK, converting a static installation into a mobile platform. It also enables the 12U open frame configuration to be moved when fully equipped. The jump is worth it when rack repositioning is required more than once during the hardware lifecycle.

Questions about this item

How much extra height will the four casters add to my 42U rack once they are installed all day?

The casters mount directly to the bottom of the 42U rack frame and raise it by the wheel diameter, letting you roll the cabinet without changing its internal U count.

Which rack model must I already own for this caster kit to bolt on correctly?

The kit is designed for the StarTech.com 42U Adjustable 4 Post Open Server Equipment Rack (4POSTRACKBK) and attaches to its existing mounting points.

Will these casters still fit if I keep my older 12U 4-post open frame rack instead of the 42U model?

No, the mounting pattern matches the 42U 4POSTRACKBK only; the 12U version uses a different hole spacing so the casters will not align.
