Middle Atlantic RSH4S4R Custom Shelf, 15.5" Deep, 4U RMS, Black

Install proprietary or non-standard devices quickly and securely with the Middle Atlantic by Legrand RSH4S4R custom rack shelf. Designed for installers and system integrators, this 4U custom shelf creates a precision opening so cameras, DVRs, encoders, and other security or monitoring gear mount flush in a standard 19in enclosure without cutting or modification. At 15.5in depth and constructed from lightweight aluminum with a textured black powder coat, the RSH4S4R combines durable aesthetics with low-profile thermal performance.

Vented rack ears and a perforated shelf bottom maintain critical airflow for surveillance and network appliances, while rear brackets lock devices in place for reliable operation in rack environments. The unit accepts components up to industry-standard widths and assembles in minutes—reducing installation time and onsite labor costs. With Middle Atlantic quality, eco certifications, and a lifetime limited warranty, this custom rackshelf is ideal for security, surveillance, AV, and IT infrastructure projects. Specify your component measurements and add the RSH4S4R to your rack build for a clean, professional result.
