Die cast aluminum NEMA enclosures are extremely rugged and yet lightweight. They are very inexpensive, easy to modify with holes, easy to wall mount and can be coated for a better appearance. The significant disadvantage is that they are expensive to tool if a manufacturer’s standard product does not meet dimensional requirements. Also, they are built for more rugged applications and are not as high style as plastics. This would be the proper enclosure when the application is not in a highly visible location or where visuals are less meaningful. It provides great durability for the price.
