Middle Atlantic RSH4A3R Custom Shelf, 15.5" Deep, 3U RMS, Black

Install non-rackmount devices as if they were native rack equipment — quickly, cleanly and securely. The Middle Atlantic by Legrand RSH4A3R Custom Shelf is a 3U custom rackshelf engineered to accept components up to 17-3/4" wide and a 15.5-inch depth, delivering a perfect, gap-free faceplate that integrates seamlessly into a standard 19" cabinet. Ideal for security, surveillance, monitoring and networking deployments, the anodized steel construction provides a professional appearance and rugged protection in control rooms and IT closets. Fully vented ears and shelf bottom help maintain optimal airflow for heat-sensitive electronics, while rear support brackets lock gear in place during service or transport. Because each unit is precision-cut from a large measured component database, installers save time and avoid costly on-site modifications. Choose the RSH4A3R to create polished, reliable rack installations for DVRs, NVRs, power supplies, switches and other critical system components. Add this custom rackshelf to your next security or AV rack build to streamline installs and improve equipment longevity.
