Middle Atlantic Skirted Caster Base 25IN. D ERK Series with Fine Floor Casters Steel - CBS-ERK-25R

Middle Atlantic CBS-ERK-25R Skirted Caster Base for ERK Series Racks

Overview

The CBS-ERK-25R is a skirted caster base designed to add rolling mobility to Middle Atlantic ERK-series open-frame racks. At 22 in wide × 25 in deep × 4 in tall, it sits below the rack footprint and keeps the installation low-profile while allowing repositioning without lifting the loaded cabinet. The 700 lb weight capacity handles fully populated AV or security equipment racks — a real consideration when a rack carries NVRs, PoE switches, and UPS units simultaneously. Fine floor casters are specified for finished or polished floor environments where standard hard-rubber casters would mark or scratch. The black wrinkle powder coat finish matches the ERK rack family's standard aesthetic. Factor the 4 in height addition into your cable management and overhead clearance calculations before ordering.

Compatibility

Designed specifically for the Middle Atlantic ERK series open-frame racks with a 25 in depth footprint. Verify your ERK rack's listed depth matches 25 in (63.5 cm) — Middle Atlantic offers ERK bases in multiple depth variants, so confirm the suffix before ordering. This base is not interchangeable with WRK, BGR, or other Middle Atlantic rack accessory series that carry different footprint dimensions. If you are building a NVR or AV equipment rack deployment where future repositioning is likely, this caster base eliminates the need to fully unload the rack to move it.

Installation Notes

The CBS-ERK-25R ships at 19.2 lbs — plan for two-person handling when attaching to a populated rack. Product weight is 17.2 lbs. The base mounts under the ERK rack frame; ensure the installation surface is level before locking casters to prevent rack lean under load. Fine floor casters are appropriate for tile, hardwood, or polished concrete — confirm suitability if deploying on uneven or heavily textured surfaces.
