Key Features and Benefits of This Locking Plug

The twist lock L5-20P configuration keeps the plug seated under vibration or accidental tugging, which matters for equipment that cannot afford unexpected power loss. Solid brass blades and a super tough nylon body resist wear from frequent plugging and unplugging in demanding settings.

Where to Use the 2311-CY Locking Plug

Suited for portable equipment, stage or event power, and industrial tools on 125V, 20 amp circuits where a standard plug risks disconnecting. Not intended for circuits or voltages outside its 125V, 20 amp, 2 pole, 3 wire rating.

Installation and Compatibility Checks

Must be paired with a matching L5-20R locking receptacle to function, so confirm the receptacle type before ordering. Its field wireable design lets an electrician terminate it onto existing cord or cable rather than replacing the entire cord set.

Additional Buying Context

UL 498 and CSA C22.2 certification confirms it meets recognized safety standards for North American electrical equipment, giving buyers assurance for both commercial and light industrial use.
