30″H x 25″W x 34″D (15 RU*) Outdoor Enclosure

The OD series outdoor enclosure is the ultimate choice for your outdoor racking requirements. Being made of our own Alumiflex®, you’ll find it noticeably lighter than steel, yet strong enough to rack even the heaviest equipment. Being designed to accommodate the weather protection of your choice, the OD series enclosures are available in NEMA 3R, 4, or 4X configurations. The additional Alumishield® (sun roof), provides superior solar protection with it’s large overhang roof design. Our own versatile strut system allows you to position the racking rails at any depth desired within the enclosure. You can rest assured your equipment is safe and secure as you pad lock the front and rear door handles, knowing they hold the three points locking system securely intact. The OD series enclosures are available in various heights and depths, and they are available in dual and triple bay versions as well. Our professional Sales staff and CAD-Engineering team are able to assist you with a state of the art design, a competitive price, and a guaranteed delivery.
