A Relay Rack is a 2-post steel structure with universal (square) mounting holes. Relay Racks are also called 2-Post Racks or Open Bay Racks.

The vertical holes spacing on Relay Racks are standardized for mounting Telco, or computer / network equipment. Relay Racks can also mount cantilever shelving for other non-rack mountable equipment.

Applicable Standard:

  • Internal dimensions to IEC 297-2 and DIN 41494, Part 1 with addition to DIN-IEC drilling in EIA standard.
  • Load carrying capacity 300kg.

Delivery Comprises:

Open Frame Structure

  • 1 set top & base frame.
  • 1 set 19? standard side frame.
  • 30 sets cage nut & screw.

Relay Rack Benefits:

  • EIA Standard 19" Rack mounts most networking equipment
  • Easily Installable
  • No doors or panels to hinder air flow
  • Compact shipping size
  • Light Weight
  • Requires less real estate then a 4-Post Rack
  • Wide availability of Relay Rack Accessories - cable management products, cantilever shelves, power strips, etc.

When a 4-Post Rack should be considered over a 2-Post Relay Rack:

  • Security - a locked enclosure would be required
  • Stability - normally a 4-Post Rack has far more stability
  • Because of their weight or center of gravity, some equipment can not be safely mounted to a 2-post rack
  • Weight - 4-post racks can mount far more weight
  • Some equipment require front & rear mounting
  • Flooring may not allow bolting of a Relay Rack base
