OCC's NEMA 3 Wall Mount Enclosures offer the same modular features of the WTC series with the added outdoor durability for outside plant functionality. The NEMA 3 series, like all OCC Wall Mount cabinets, can be ordered empty or can be easily customized to fit any exact specification. Ideal for smaller OSP and inside premise applications, the OCO6N and OCO12N are a perfect fit with the additional benefit of being NEMA Type 3 compliant.
