Middle Atlantic CBS-WRK-27 Skirted Caster Base for 27-Inch WRK Racks
Overview
The CBS-WRK-27 is a skirted wheelbase designed to add mobility to Middle Atlantic WRK-series racks with a 27-inch depth footprint. Rather than anchoring a rack permanently to a floor, this base lets you roll the entire assembly — casters included — for staging, repositioning during system commissioning, or accessing rear cabling runs without breaking down the build. At 4 inches tall and rated for 1,300 lbs (589.7 kg), it supports fully loaded racks without flex or sag. The black wrinkle powder coat finish matches standard Middle Atlantic rack aesthetics for a clean, integrated appearance in equipment rooms and broadcast environments.
Compatibility
The CBS-WRK-27 is purpose-built for the Middle Atlantic WRK rack series at 27-inch depth. It is not a universal base — the mounting footprint and skirt geometry are matched to WRK-series rails specifically. Verify your WRK model's listed depth is 27 inches before ordering; Middle Atlantic offers parallel CBS-WRK variants for other depths in the same series. This base is not compatible with ERK, BGR, or other Middle Atlantic frame families without confirming dimensional fit independently.
Installation Notes
The CBS-WRK-27 ships with casters pre-specified for the assembly — no separate caster sourcing required. Unit weight is 21.6 lbs (9.8 kg), so two-person handling is practical for positioning under a loaded rack. The 4-inch installed height raises the rack floor accordingly — account for this when planning vertical cable management or bottom-entry conduit runs. Shipping weight is 23.6 lbs (10.7 kg).
