Middle Atlantic 44 Space (77IN. ) 26IN. Deep Configured AV Rack ***Drop Ship Only*** - MRK-4426-AV

Middle Atlantic MRK-4426-AV 44U Pre-Configured Floor-Standing AV Rack

Overview

The MRK-4426-AV is a 44-space (77.13 in. usable height), 26-inch-deep floor-standing rack engineered specifically for Pro AV deployments — think large-format AV over IP systems, matrix switchers, amplifier arrays, and multi-channel processing gear that needs both physical depth and substantial load headroom. At 2,500 lbs UL-listed load capacity with a 10,000 lb static weight capacity, this rack handles fully loaded AV infrastructure without flex or rack-rail sag. The 24-inch usable depth accommodates full-depth AV processors and network gear that won't fit in shallower 21-inch racks. A rear door and side panels are included, enabling structured cable management and basic airflow containment. The 550 CFM airflow rating gives you a baseline for sizing supplemental fan trays or active cooling if the load heat density requires it. Made in the USA and ASCE 7-10 seismic rated (UL Listed) with a 1,050 lb seismic load capacity — a real consideration for installations in California, Pacific Northwest, or any jurisdiction requiring seismic compliance on rack systems.

Compatibility

Built on standard 19-inch panel width with 10-32 threaded rack rails — compatible with virtually all 19-inch rackmount equipment from vendors including Crestron, AMX, Extron, QSC, Crown, Biamp, and standard 1U/2U/4U network gear. The 44 RU capacity suits large AV racks in boardrooms, auditoriums, control rooms, and equipment closets where a single rack must house both AV processing and supporting IT infrastructure. Not a relay rack or open-frame design — this is a fully enclosed cabinet, so confirm your cable routing and front/rear access plan before specifying in tight equipment rooms. Ganging is not supported (Gangable: No), so multi-rack rows require individual units.

Installation Notes

Shipping weight is 246 lbs — plan for two-person delivery and positioning. Seismic rating is ASCE 7-10 compliant; consult local code requirements for anchor/fastener specifications at the installation site. Confirm door swing clearance: at 23.25 in. wide with a rear door, allow adequate aisle depth front and rear. Drop ship only — direct delivery to job site.
