Middle Atlantic CSA-20 Rack Chassis Support Bracket

Overview

The Middle Atlantic CSA-20 is a 20-inch deep rack chassis support bracket designed to bear the weight of heavy rackmount equipment that standard rack ears alone cannot adequately support. At a rated 100 lb (45.4 kg) capacity, the CSA-20 handles dense chassis — power distribution units, AV amplifiers, network appliances, and similar gear — that would otherwise place excessive cantilever stress on front-panel mounting points. The bracket mounts inside the rack to provide a rear load-bearing shelf without consuming a full rack unit of vertical space: at 1.75 in (4.4 cm) tall, it fits in the dead space alongside installed equipment rather than displacing usable rack space. A black powder-coat finish blends with standard Middle Atlantic rack enclosures and most third-party open-frame and enclosed racks.

Compatibility

The CSA-20 is compatible with Middle Atlantic rack enclosures and any standard EIA-310 19-inch rack that provides rear vertical rail or side-panel attachment points. The 20-inch depth suits Middle Atlantic WRK, BGR, and ERK series rack enclosures with interior depths of 20 inches or greater. It is also field-applicable to third-party racks from Chief, Chatsworth, Belden, and similar manufacturers where internal depth accommodates the full 20-inch bracket. When specifying for rack accessories and chassis support applications, verify your rack's internal usable depth before ordering — a 20-inch bracket requires at least 20 inches of clear interior depth from the front rail to the rear obstruction. Four mounting points distribute the load across the bracket-to-rack interface, reducing point stress on side panels or rear rails under full 100 lb load.

Installation Notes

The bracket ships as a single unit (Package Qty: 1) and weighs 2.8 lbs shipping weight. Width is 3 in (7.6 cm), so confirm your rack's internal side clearance accommodates the bracket body alongside installed equipment. No special tooling is specified beyond standard rack installation hardware; fasteners appropriate to your specific rack model are required and not included. For rack enclosure builds where multiple heavy chassis require support, plan bracket positions before final equipment layout — the 1.75 in height means brackets can be positioned in unused vertical gaps between units without sacrificing rack unit count.
