Easy Twist Lock System has been designed to make hook-up quick and easy. Just connect the cordset (with an easy twist lock locking ring installed) to the inlet and turn the locking ring less than a quarter of a turn. The tabs on the locking ring lock into the inlet for a positive watertight hook-up while eliminating any chance of cross threading. The locking ring features lock locators positioned at 180° to improve finger grip during attachment. Inlets have a threaded boss that will accept threaded cordsets as well. Contoured inlet features a waterproof, Soft Touch cap design. Hinge is designed to stay open in the upright position during hook-up. A "soft touch" allows it to close. Features 8-way right angle rear safety closure.
