Middle Atlantic 4 Space 23IN. Deep VTR Sliding Rackshelf - SS4-23VTR

Middle Atlantic SS4-23VTR 4-Space 23-Inch Deep VTR Sliding Rackshelf

Overview

The Middle Atlantic SS4-23VTR is a 4U sliding rackshelf built for rack-mounted equipment that needs to be pulled forward for service access — NVRs, DVRs, CPUs, and similarly deep appliances that don't ship with integrated rack ears. At 23 inches of usable depth and a 75 lb weight capacity (50 lb UL-rated load), the SS4-23VTR handles most commercial rack accessory installations without a secondary support shelf. The black powder-coat finish blends into standard equipment racks. If you're racking surveillance recorders or AV appliances that require periodic hands-on access without full removal, this shelf eliminates the need to disconnect cabling just to reach rear ports.

Compatibility

Fits any standard 19-inch EIA rack with 4U of open space — including Middle Atlantic rack enclosures and open-frame racks from other manufacturers. The 23-inch depth accommodates full-depth 1U and 2U appliances including most commercial NVRs in the network video recorder category (typical chassis depth 16–20 inches), rackmount PCs, KVM switches, and UPS units within the weight limit. Not suited for equipment exceeding 75 lbs or racks shallower than 24 inches front-to-back (the shelf itself is 23 inches plus rail hardware). Four mounting points secure the shelf to standard rack rails — no adapter plates required for EIA-standard 19-inch rails.

Installation Notes

The SS4-23VTR occupies 4 rack units (8.71 inches vertical). Verify rack space before ordering — 4U is a significant commitment in a fully loaded enclosure. Weight capacity is 75 lb total (50 lb UL-listed load rating); stay at or below the UL figure for installations subject to inspection. Shipping weight is 17 lbs, so factor that into freight for multi-unit orders. For deployments pairing this shelf with a rack enclosure, confirm the enclosure's interior depth leaves clearance for the slide mechanism beyond the 23-inch shelf surface.
