Industrial Locking Plug

The Hubbell HBL2447 is a NEMA L5-15P locking plug rated for 15 A at 125 V AC. Its yellow elastomer housing resists chemicals and impact. Industrial-grade construction and a grounded, polarized design suit production floors, stage lighting rigs and portable equipment that must stay connected under vibration.

Replaces worn twist-lock plugs

Swapping a cracked or loose straight-blade connector for this locking version eliminates accidental disconnects when cables are tugged. The jump is worth it whenever a machine or light tree moves during operation and a standard plug cannot hold. Screw terminals accept conductors from .3 in to .655 in outer diameter.

Fits standard L5-15 receptacles

The three-blade, two-pole configuration mates with any matching L5-15R outlet. No special wiring harness or adapter is required. The straight orientation keeps the cable exit in line with the panel, freeing space behind racks or in tight conduit runs where angled plugs would bind.

Questions about this item

What cable diameters does the HBL2447 locking plug accept?

The plug fits cables from .3 in to .655 in outer diameter, so verify your cord falls in that range before wiring.

How do the screw terminals connect, and what step is often missed?

Strip each conductor, insert into the terminal, tighten the screw firmly, then torque the cord-grip screws to clamp the jacket — skipping the grip leaves the cable loose.

When should the yellow elastomer housing be replaced?

Replace the plug if the housing shows cracks, chemical damage, or the locking blades no longer seat securely in the receptacle.
