Middle Atlantic CBS-5R Slim 5 Skirted Caster Base — Fine Floor, 20 in. Deep

Overview

The CBS-5R is a skirted caster base designed specifically for Middle Atlantic Slim 5 Series racks. At 4 in. tall with a 400 lb weight capacity, it gives a loaded rack full mobility without a dedicated raised-floor infrastructure — useful during equipment staging, data center walkthroughs, or ongoing rack repositioning in active server rooms and AV equipment spaces. The black wrinkle powder coat finish matches standard Middle Atlantic rack aesthetics. The CBS-5R ships at 19.05 lbs, with a product weight of 17 lbs — light enough to install solo before the rack is loaded.

Compatibility

Designed for the Middle Atlantic Slim 5 Series rack line. The base footprint measures 19.13 in. wide × 20 in. deep (48.6 cm × 50.8 cm), matching the Slim 5 chassis dimensions. Verify your specific Slim 5 rack model's base footprint against these dimensions before ordering — the CBS-5R is not interchangeable with Middle Atlantic's standard-depth or wide-body rack series. The Fine Floor caster style is suited for finished flooring surfaces such as raised access tile, polished concrete, and hardwood — not intended for rough or uneven subfloor installations where locking heavy-duty casters would be more appropriate.

Installation Notes

The base adds 4 in. (10.2 cm) to the overall rack height — account for this in overhead clearance planning, particularly in ceiling-constrained closets or under cable management trays. Casters are included; confirm all four are fully engaged and locked before loading equipment. The 400 lb capacity covers a fully populated shallow-depth network rack, but verify your loaded rack weight against this limit before use. The wrinkle powder coat finish is scratch-resistant but not suitable for wet or high-humidity environments without additional rack enclosure protection.
