Middle Atlantic 5-37-26 Slim5 37U Knockdown Open Frame Rack
Overview
The Middle Atlantic 5-37-26 is a 37U, 26-inch-deep knockdown open-frame rack enclosure from the Slim5 family, built for AV, security, and network equipment rooms where a permanent welded cabinet is impractical or overkill. At 46 lbs assembled and shipping at 57.52 lbs, it ships flat and assembles on-site — a practical advantage in installations with elevator restrictions or tight staging areas. The 5-37-26 uses Middle Atlantic's interlocking corner joint system, which distributes racking stress across the joint geometry rather than relying solely on fasteners, delivering a UL-verified 400 lb load capacity in a frame-only form factor. TAA-compliant and manufactured in the USA, it qualifies for federal procurement and GSA-schedule projects without additional sourcing documentation.
Compatibility
Accepts any standard 19-inch EIA-310 rack equipment via 10-32 threaded rail — the dominant rail standard across managed network switches, NVRs, UPS units, patch panels, and AV signal processors. The 26-inch usable depth (64.75 in usable height across 37 RU) accommodates most 1U–4U network and security appliances without front-to-rear extension rails. Gangable design allows side-by-side pairing with additional Slim5 frames — useful when a single 37U column isn't enough and a full enclosed cabinet isn't warranted. Compatible with the broader Middle Atlantic rack accessory ecosystem including cable management, blanking panels, and PDU mounting options designed for the Slim5 rail profile.
Installation Notes
Knockdown assembly requires no special tooling beyond standard hand tools — no welding, no specialized fixtures. Level the frame on the finished floor before torquing corner joints; the interlocking geometry self-squares during assembly, but shimming may be needed on uneven concrete. The 19.13-inch overall width fits standard floor grid spacing in raised-floor data rooms. Federal country-of-origin documentation (USA) is available for procurement compliance submissions. TAA designation is confirmed UL Listed.
