Middle Atlantic MRK-4026 40U 26-Inch Deep Gangable Floor Rack
Overview
The Middle Atlantic MRK-4026 is a 40-space, 26-inch-deep floor-standing rack built for AV, security, and IT infrastructure deployments where structural integrity and future expansion matter. The MRK-4026 ships as a frame-only configuration — 22 inches wide, 76.13 inches tall overall, with 70.13 inches (40 RU) of usable panel height — and is finished in black. The 26-inch external depth yields 24 inches of usable interior depth, sufficient for shallow AV amplifiers, network switches, NVRs, and patch panels without crowding cable management. TAA compliant and manufactured in the USA, this rack suits federal and government-adjacent deployments where country-of-origin documentation is required. Drop-ship fulfillment only — plan lead time into project scheduling.
Compatibility
Accepts any standard 19-inch EIA-310 panel equipment on 10-32 threaded rack rails — the industry default for AV receivers, NVRs, PoE switches, patch panels, UPS units, and server 1U/2U appliances. The gangable design allows side-by-side joining of multiple MRK-series frames into a unified multi-bay array, useful in control rooms, NOCs, or large AV head-end closets where a single 40U column is insufficient. The rear door included on this model supports airflow management and cable security in populated installations. No side panels are included; add Middle Atlantic side panel accessories separately if the deployment requires a fully enclosed cabinet. Works with standard rack-mount accessories from any vendor conforming to EIA-310 rail spacing.
Installation Notes
Seismic rating per ASCE 7-10 requires proper floor anchoring — verify local code requirements before installation, as seismic certification is load-condition dependent and not a substitute for site-specific engineering in high-seismic zones. UL-listed load capacity is 2,500 lbs (1,134 kg); the structural weight capacity ceiling is 10,000 lbs (4,535 kg), but the UL rating is the operationally relevant figure for equipment loading. Shipping weight is 138 lbs — account for lift equipment or two-person installation. Frame-only configuration means rails, blanks, and cable managers are sourced separately.
