Middle Atlantic R4CN-4524B 4-post Open Frame Rack

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND R4CN-4524B is an open-frame, four-post equipment rack designed for structured AV, IT, and low-voltage installations. Built in the R4 Series, it provides a rigid mounting platform for rackmount equipment without the enclosure of a closed cabinet. The open-frame design allows unrestricted airflow and full front, rear, and side access to installed gear. Cage nut hardware is included, enabling standard EIA-style rackmount compatibility across a wide range of equipment form factors. This rack is typically specified and installed by AV integrators, low-voltage technicians, and IT infrastructure professionals.

The R4CN-4524B is suited for server rooms, equipment closets, broadcast racks, and commercial AV installations where ventilation and multi-sided access are priorities over physical security. The four-post configuration supports front and rear rail mounting, distributing equipment load and accommodating deep rackmount devices such as servers, patch panels, amplifiers, and signal processors. Its open construction also simplifies cable management and future equipment additions.
