Commercial Electrical Enclosures with Knockouts

Hammond Manufacturing Commercial Electrical Enclosures with Knockouts are ideal for commercial building construction and light industrial needs. These UL-listed enclosures are available in several NEMA ratings, including Type 1 and Type 3R. The Type 1 enclosures are suitable for use as a junction, pull, or switch box in general-purpose indoor commercial applications, while the Type 3R junction boxes provide protection against rain, sleet, snow, and dripping water. Hammond Manufacturing Commercial Electrical Enclosures feature knockouts on the bottom of the enclosure or on all four sides for design flexibility.
