June 5, 2013 – Arlington’s one-piece, non-metallic screw-on connectors are now available in 1-in. trade sizes. Designed for use on non-metallic, liquid-tight conduit (Type B), they screw on to conduit by hand. The screw-on connectors ship fully assembled; they overlap conduit, hiding cut ends, and promise a reliable, UL-listed liquid-tight seal. They are available in 180º (straight) and 90º, in grey or black.
