Hubbell HBL2513BK Locking Connector

The Hubbell HBL2513BK is a 20 A locking connector rated for L21-20R service, built for installers and technicians who need a secure power link in commercial or light-industrial environments. Its black finish and robust housing suit permanent installations where accidental disconnection must be avoided.

20 A capacity with L21-20R pinout

The device handles 20 A continuously on a 21-pole configuration, giving reliable headroom for single-phase loads up to its rated current. It runs out of capacity when demand exceeds 20 A or when a different pin arrangement is required, so it cannot serve higher-amperage or alternate-polarity circuits.

Superior cord grip and dust shield

A superior cord grip design protects terminations from excess strain during pulling or vibration, while the clear, funnel-shaped wire entry speeds termination and reduces wiring errors. An integral dust shield keeps the wiring chamber free of contaminants, supporting long-term reliability in dusty or dirty locations.

Questions about this item

Will this L21-20R connector mate with my existing L21-20P plug on the same 20 A circuit?

Yes, the L21-20R is the receptacle side of the NEMA L21-20 locking pair, so it locks securely with any L21-20P plug rated for 20 A.

How can I verify the wiring is correct after I terminate the conductors?

The clear funnel-shaped wire entry lets you visually confirm each conductor is fully seated before tightening the terminals, and the integral dust shield snaps closed to show the chamber is sealed.

Does the package include a matching L21-20P plug or only the HBL2513BK connector body?

Only the black HBL2513BK locking connector body is supplied; a matching L21-20P plug must be purchased separately.
