Middle Atlantic MRK-2431 24RU Gangable Floor Rack with Rear Door
Overview
The Middle Atlantic MRK-2431 is a 24-space (24RU), 31-inch deep gangable floor rack designed for AV, security, and IT equipment installations where structural integrity, depth, and side-by-side expansion matter. At 48.13 inches tall with 42.13 inches of usable height and a 29-inch usable depth, the MRK-2431 accommodates deep equipment like NVRs, servers, and multi-channel amplifiers without forcing you to cut corners on cable routing. The frame ships without side panels — intentional for rack enclosure builds that gang multiple units side by side, letting you configure the footprint to match the room. Includes a rear door for controlled access to patch panels and power distribution, and finishes in black.
Compatibility
Accepts any standard 19-inch rack-mount equipment on 10-32 threaded rails — the industry-standard thread for Middle Atlantic rack systems and compatible with virtually all 1U–4U security and AV gear: NVRs, PoE switches, KVM units, UPS modules, patch panels, and rack-mount power strips. The gangable design pairs directly with other MRK-series frames, letting you expand rack capacity incrementally without reconfiguring the existing build. TAA-compliant construction makes it eligible for federal, state, and municipal procurement where country-of-origin rules apply — manufactured in the USA.
Installation Notes
Seismic rating per ASCE 7-10 with UL-listed seismic load capacity supports deployments in seismic zones where code compliance is required — verify local AHJ requirements before specifying. UL-rated static load is 2,500 lbs; total weight capacity is 10,000 lbs, so this frame is not the weak point in any realistic NVR or server stack. Frame-only configuration means side panels, top panels, and doors (beyond the included rear door) must be ordered separately if a fully enclosed rack enclosure is needed. The 22-inch overall width and 31-inch depth require adequate floor clearance; confirm ceiling height against the 48.13-inch overall height before drop-shipping to site. Ships direct from the manufacturer — confirm delivery access and site-readiness before placing the order.
