The SR-WIREMGT-4D-1U is up to the task! High-grade ABS plastic D-Rings are mounted to a 1U steel rack plate for quick installation. Put one of these at the top of each rack to easily group and direct simlar cables. The SR-WIREMGT-4D-1U easily tracks bundles of wires behind the rack for a clean finished look. With holes in the middle of the plate, you can also branch wires off to equipment directly behind it. This is ideal for routing speaker cables to multi-channel amplifiers. The D-rings are pre-installed for horizontal management. Look closely and you will notice you can pull them out and reposition for vertical wire management too.
