The coupling provides a flexible, watertight connection, accommodating axial or parallel movement of up to 3/4 inch and angular movement of up to 30° from normal position. ships complete with an Erickson® conduit union to significantly reduce installation time and effort and includes a stainless steel inner sleeve for extreme durability, protection and easier wire pulling. The hubs are zinc-plated and then coated with aluminium acrylic paint for dual-layer corrosion protection. In addition, the copper ground mounting plates and internal grounding bonding jumper are entirely enclosed inside the coupling for added security against vandalism and theft.
