Middle Atlantic CBS-5-26 Skirted Caster Wheelbase for Slim 5 Series Racks
Overview
The CBS-5-26 is a skirted caster wheelbase designed specifically for Middle Atlantic Slim 5 Series ERK racks with 26-inch depth. It adds four locking casters to a fixed rack installation, converting a stationary enclosure into a mobile unit — useful in broadcast, AV integration, and security equipment rooms where racks need to be repositioned without breaking down the entire assembly. At 4 inches tall and rated for 400 lbs (181.4 kg), the CBS-5-26 handles fully loaded rack enclosures without flexing or shifting. The black wrinkle powder coat finish matches standard Middle Atlantic rack aesthetics. Product weight is 17.1 lbs (7.8 kg).
Compatibility
The CBS-5-26 is built exclusively for the Middle Atlantic Slim 5 Series ERK line at 26-inch depth. It will not fit standard-depth ERK frames, wider enclosures, or other rack families. Verify your rack's depth is 26 inches and the series is confirmed Slim 5 before ordering — Middle Atlantic offers parallel caster base SKUs for other depths and series, and cross-fitting between them is not supported. If your ERK rack is a different depth (e.g., 21-inch or 30-inch), a different CBS variant is required. For integrators building out a rack accessory stack, confirm the base series designation on the rack's label or order documentation before selecting this SKU.
Installation Notes
The CBS-5-26 mounts beneath the ERK enclosure as a base platform — the rack sets directly onto the wheelbase frame. Width measures 19.13 inches (48.6 cm), matching standard 19-inch rack footprint with side clearance. Height adds 4 inches (10.2 cm) to the overall rack stack, which affects front-access ergonomics and ceiling clearance calculations in tight equipment rooms. Casters lock individually; engage all four locks once the rack is positioned to prevent drift on sloped or uneven flooring. A rack installation guide covering load balancing and floor ratings is recommended for deployments in raised-floor data environments. Shipping weight is 19.05 lbs (8.6 kg).
