Marinco® Power Inlets Easy Lock - Marincos exclusive Easy Lock System has been designed to make hook-up quick and easy. Just connect the cordset (with an Easy Lock locking ring installed) to the inlet and turn the locking ring less than a quarter 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. Easy Lock inlets have a threaded boss that will accept threaded cordsets as well. The Easy Lock system is a standard feature on some Marinco® 30 amp and 50 amp inlets and cordsets. The covers on all Marinco® inlets are designed to stay hinged open when the cover is lifted up. This allows the boater to connect their shore power cord while the cover remains open and out of the way. A soft touch unlocks it for closing.Blades are nickel plated brass for maximum corrosion resistance. Interior hardware is marine-grade stainless steel.
