This Hubbell industrial female Twist-Lock® connector provides a secure locking connection for 50A, 125/250V power distribution on demanding job sites. Its tough nylon housing resists impact, while the heavy-duty two-piece cord clamp provides strain relief for cord-mounted connections. Designed for indoor dry use unless protected by additional means, it features oversized brass contacts to help minimise operating temperature.
