Hubbell Incorporated HBL2311S Locking Plug L5-20P 20 A 125V AC video accessory

Hubbell HBL2311S Locking Plug

The Hubbell HBL2311S is a 20 A 125V AC locking plug built for secure power connections in professional audio and video environments. Its L5-20P configuration suits equipment that requires a twist-lock connection to prevent accidental disconnection during operation. The impact-resistant shroud protects the blades from bending or breaking when the plug is handled or stored. This accessory is intended for installers and technicians who need reliable, industrial-grade power termination.

Compatibility checks before ordering

Verify that the device you are powering accepts an L5-20P inlet rated for 20 A at 125V AC. Confirm the cord you plan to attach matches the plug’s conductor capacity and that the cable diameter suits the integral cord grip. Ensure the installation location can accommodate the ribbed nylon housing and that local electrical codes permit this locking type for the intended circuit. The integral dust shield helps keep the wiring chamber clean during and after assembly.

Behaviour under sustained load

The ribbed nylon housing provides impact and chemical resistance while maintaining a secure grip during extended use. The superior cord grip design protects terminations from excess strain when the connected cable is subjected to movement or vibration over time. An impact-resistant shroud continues to guard the blades against physical damage throughout the plug’s service life. The integral dust shield preserves the wiring chamber from contaminants during prolonged operation.
