The R412-3830B R4 Series 30" Deep 38U Four-Post Open-Frame Rack from Middle Atlantic is a heavy-duty rack designed to accommodate deeper heavier components than two-post open-frame racks. This unit is ideal for servers, networking equipment, routers, and switches, among many other possibilities. This model features 3/16" thick extruded aluminum rails with 12-24 threads. The rack frame is made of 16-gauge steel.

Its open design promotes airflow and ensures that your equipment stays cool, thereby prolonging its useful life. The rack can also be ganged to additional four-post or two-post open-frame racks, making for virtually unlimited expansion possibilities.

The rack may be configured with the base on the inside to save rack space, or on the outside for increased stability. This unit will also accept 6, 9, or 12" cable ladders. It features numerous locations for mounting optional power units, cable-lacing strips, and additional rack rails, among many other separately available accessory items.

This rack will support up to 2500 lbs of equipment. Mounting hardware is included with the unit.
