They offer an iron construction for durability and have an electro galvanised / aluminium acrylic paint finish for superior corrosion resistance. These units have tapered threaded hubs for providing a secure and watertight connection between the conduit and the outlet body. They are NEMA rated for water-and-dust protection and are available in hub sizes of 1/2 and 3/4 inches.
