Middle Atlantic Caster Base for Wmrk 42IN. Deep Rack Includes 4 Casters - CBS-WMRK-42

Middle Atlantic CBS-WMRK-42 Caster Base for 42-Inch Deep Rack

Overview

The CBS-WMRK-42 is a bolt-on caster base designed specifically for Middle Atlantic WMRK-series open-frame racks in the 42-inch depth configuration. At 4.03 inches tall and 22.78 inches wide, it adds floor mobility without consuming usable rack units — the right answer when equipment needs to roll out for rear-access servicing in tight machine rooms, broadcast equipment bays, or AV integration racks. The black wrinkle powder coat finish matches the WMRK rack family. If your deployment involves periodic maintenance access behind the rack, this base eliminates the need to fully dismount or shift the frame. The unit ships at 35 lbs with the caster assembly; plan accordingly when scheduling single-person installs.

Compatibility

Designed exclusively for the Middle Atlantic WMRK rack series at the 42-inch depth (106.7 cm). Do not attempt to pair with WMRK racks in shorter depth configurations — the footprint is matched to the 42-inch frame specifically. This base is not cross-compatible with Middle Atlantic WRK, ERK, or BGR series frames. If you are configuring a complete open-frame rack system, verify your WMRK rack depth matches before ordering. The CBS-WMRK-42 integrates into the WMRK base mounting points and does not require additional adapters within the correct series pairing.

Installation Notes

The base mounts to the underside of the WMRK rack frame using the rack's existing base attachment points. At 22.78 inches wide and 42 inches deep, confirm floor clearance and aisle width before rolling a populated rack — 4 casters are included and the unit weight of 33 lbs adds to your total loaded rack weight for floor-load calculations. A rack accessories kit or additional leveling feet may be needed if the final installation position requires the rack to be stationary after positioning. No power or cabling is involved in the install. Review rack planning guidelines for floor load and aisle clearance requirements in high-density deployments.
