ENCLOSURE
NEMACO™ submersible enclosures & junction box designs are the right-rated solution when the installation environment goes underwater, available in NEMA 6P, IP67, and IP68 configurations to match the submersion depth, duration, and certification requirements of the application. Every unit is tested for 24-hour submersion at 15+ feet to validate watertight integrity before leaving the facility. American made in stainless steel, aluminum, and fiberglass, these UL Listed enclosures are a specification-ready choice for coastal, utility, flood-prone, and subsea installations where long-term sealing performance is non-negotiable
