The unique design of traditional relay racks can be a problem for cantilever shelf designs. Middle Atlantic's center-mount shelf solves this problem by evenly distributing the weight of equipment to both sides of the rack rail. Constructed with 16-gauge steel, this shelf provides a full 18 inches of surface depth and only uses 2 rack spaces. The vented base allows proper airflow to stored equipment. Each unit is finished in a durable black powder coat and individually boxed. Large volume quotations are available; Contact us today!
