Middle Atlantic CBS-MRK-26 Skirted Caster Wheelbase for MRK Series Racks
Overview
The CBS-MRK-26 is a skirted caster wheelbase designed to add mobility to Middle Atlantic MRK-series rack enclosures configured at 26 inches of usable depth. At 4 inches tall and rated to 1,300 lbs (589.7 kg), the CBS-MRK-26 handles fully populated racks without flexing — a practical requirement when repositioning loaded equipment in broadcast, AV integration, or security head-end rooms. The black wrinkle powder coat finish matches standard MRK enclosure aesthetics. The integrated skirt panels conceal the caster mechanism and cable entry points at floor level, delivering a finished appearance appropriate for client-facing machine rooms and control suites.
Compatibility
Designed exclusively for rack enclosures in the Middle Atlantic MRK series at 26-inch depth configuration. Confirm your MRK rack's nominal depth before ordering — Middle Atlantic offers CBS wheelbase variants for other depth configurations, and cross-depth fitment will result in a dimensional mismatch. The 20.88 in (53 cm) width aligns with standard MRK footprint dimensions. Not compatible with other Middle Atlantic series (such as ERK, BGR, or WMRK) or third-party rack enclosures.
Installation Notes
Footprint dimensions are 20.88 in wide × 24.25 in deep × 4 in tall. The wheelbase ships at 23.8 lbs (10.8 kg); plan accordingly for two-person install when the rack is already loaded. Position the enclosure onto the wheelbase before final population where floor loading or clearance is a constraint — the 1,300 lb capacity is a static load rating. Verify caster lock engagement after positioning; the skirted design means visual confirmation of caster state requires deliberate inspection at floor level.
