Overview
Chatsworth Products 55053-703 is a Standard Rack designed to support rack-mount telecommunications and networking equipment in equipment rooms, network closets, and data centers. Its two-post open-frame construction provides access to installed equipment while maintaining a compact mounting profile for patch panels, network switches, and compatible cable-management accessories.
The manufacturer identifies this model as a 45U rack with 19-inch EIA equipment mounting width and a 3-inch (76 mm) mounting-channel depth. The rack is constructed from lightweight aluminum and finished in black. Integrated grounding provisions support connection to an appropriate equipment grounding system, while numbered rack spaces help installers position equipment accurately.
The rack ships unassembled in a single carton and uses a bolt-together assembly design. Threaded mounting holes simplify equipment installation without requiring cage nuts for the rack's equipment-mounting positions. Floor-mount holes are provided for securing the rack using a compatible installation kit.
This open-frame rack is intended for equipment designed for two-post mounting. Before deployment, verify equipment mounting requirements, total installed weight, rack anchoring, grounding, and the need for separate vertical or horizontal cable managers.
