Hubbell’s industrial Twist-Lock® male plug provides a secure locking connection for generators and temporary power distribution on demanding job sites. Its impact-resistant nylon housing and stainless steel shroud help protect the device and restrict mismating, while the heavy-duty two-piece cord clamp provides strain relief. High-pressure box terminals grip conductors without damaging strands.
