Middle Atlantic 5-43 43RU Slim 5 Series Open Frame Rack
Overview
The Middle Atlantic 5-43 is a 43RU knockdown open frame rack from the Slim 5 Series, measuring 19-1/8 inches wide with 20 inches of usable depth — built for AV equipment rooms, security head-end closets, and IT infrastructure deployments where a full-depth enclosure isn't needed but a structured, high-capacity mounting solution is. The 5-43 ships as a frame-only knockdown assembly, so it can be transported through tight doorways and assembled on-site without specialized tools. With 75.25 inches of usable mounting height across all 43 rack units, this frame accommodates dense NVR, patch panel, and server stacks. Rack hardware uses standard 10-32 threaded rails — the industry default for network video recorders, patch panels, and AV gear. TAA-compliant and UL Listed with a 400 lb UL-rated load capacity, the 5-43 qualifies for government and institutional procurement projects requiring domestic sourcing (manufactured in the USA) and safety certification.
Compatibility
The 5-43 accepts any standard 19-inch EIA-310 rack equipment using 10-32 fasteners — this covers the full range of Middle Atlantic accessories including blanks, shelf panels, cable management, and power distribution units. It is also compatible with rack-mount NVRs from Hikvision, Hanwha, Axis, i-PRO, and similar manufacturers whose 1U–4U appliances ship with standard rack ears. The gangable design allows multiple 5-43 frames to be bolted side-by-side for expanded deployments. Pair with a rack-mount PoE switch or patch panel to build a self-contained security head-end. Review the rack and enclosure buying guide for depth, load, and ventilation considerations before specifying.
Installation Notes
Knockdown construction means the frame arrives flat-packed at 49.8 lbs shipping weight and assembles on-site — useful when elevator or doorway clearance is a constraint. Finished width is 19.13 inches; verify your floor space accommodates side-to-side cable management if gangable installations are planned. The 20-inch usable depth suits shallow equipment but will not accommodate deep servers or UPS units exceeding that dimension — measure your deepest chassis before specifying. 10-32 cage nuts and mounting screws are typically required and may not be included; confirm hardware contents before installation day.
