Constructed from die-cast aluminum, this 1-inch diameter service cap offers excellent strength and corrosion resistance, making it ideal for outdoor use in wet and exposed environments. Designed for use with NM (Non-Metallic) and SE (Service Entrance) cables, this service entrance head acts as a transition point where overhead service wires enter a building through rigid, IMC, or EMT conduit. It features a clamp-on design that allows for quick and easy installation on both threaded and unthreaded 1-inch conduit?no special tools or threading required. This versatility simplifies field installation and accommodates a variety of service configurations. The cap includes a high-quality phenolic insulator with five knockout holes: two 7/16-inch and three 1/2-inch openings?allowing for flexible cable routing and compatibility with multiple wire gauges. The insulator prevents electrical contact between conductors and the metal housing, ensuring safe and reliable performance in live-service applications. The die-cast aluminum body provides robust protection against moisture, dust, and mechanical impact, while its silver finish enhances heat dissipation and blends with standard electrical enclosures. Rated for wet locations, this service entrance head is UL and CSA listed, meeting rigorous safety standards for outdoor electrical installations. Its compact size measures 2.75 inches in length and weighs just 0.300 pounds, offering a lightweight yet durable solution for service mast and weatherhead applications.
