4-Post Open Frame Rack DC4R Series

2,000 lbs (907 kg) Weight Capacity

The Hammond DC4R Open Rack series is one of the most economical solutions to house IT equipment in wiring closets or data centers. In situations where the wiring closet itself is under lock and key and accessed by a limited number of people, full cabinets having locking doors and side panels may not be required resulting in a significant cost savings.
