Key Features and Benefits

The RDA Series Rack Rail Depth Adapter Kit provides a simple way to reposition rack-mounted equipment by up to 4 inches without modifying the rack or replacing mounting rails. By moving equipment forward or backward, the adapters improve cable bend radius, create additional clearance for connectors, and simplify the installation of patch panels, network switches, and other lightweight rack equipment.

Compatible with standard 19-inch EIA-310-E mounting rails, the RDA Series also converts round-hole and threaded rails into square-hole mounting, making it an ideal solution for retrofit projects and mixed rack environments. Manufactured in North America, the RDA Series offers an easy, cost-effective way to solve common rack installation challenges.
