Our take on the Hubbell HBL2310ST Locking Receptacle

The Hubbell HBL2310ST is a single-gang twist-lock receptacle rated 20 A at 125 V AC, wired for NEMA L5-20R plugs. It is a commercial/industrial part, not a household outlet: nylon housing, brass contacts, spring termination to keep stranded wire from relaxing, and a flush screw mount with no wall plate. At $11.92 at Energy Avenue as of November 4, 2026, it sits at the low end of its recent range across the 5 stores that stock it new.

What reviewers say

Reception is thin because this is a spec-grade industrial part rather than a consumer product. Electricians and maintenance users who buy Hubbell twist-lock devices generally rate them as durable, well-built connectors that hold up in vibration-prone equipment.

Pros
  • Solid build and firm plug lock
  • Reliable contact over years of service
  • Clear NEMA labeling
Cons
  • Price higher than generic twist-lock brands
  • Needs a separate plate and box
  • Easy to buy the wrong NEMA configuration

Questions and answers

Is the HBL2310ST worth it over a cheaper twist-lock receptacle?
For industrial or rack power, yes: Hubbell's brass contacts and spring termination are built for repeated connect/disconnect and vibration. A generic L5-20R saves a few dollars but is the part most likely to loosen or fail.
What plug fits this outlet?
Only a NEMA L5-20P twist-lock plug, rated 20 A at 125 V. A standard household 5-20P plug will not fit, and an L5-15P will not lock in.
Does it come with a wall plate?
No. The listing is the receptacle only, with no cover or plate. You need a compatible single-gang plate and box for a finished install.
Can it be used outdoors or in a wet location?
No. It is rated IP20 and NEMA 1 for indoor dry use. Outdoors it needs a weatherproof enclosure and cover rated for the location.
Is this the same as an L5-20R outlet?
Yes. L5-20R is the NEMA configuration; the HBL2310ST is Hubbell's part number for that receptacle in black nylon.
When is the best time to buy it?
Electrical supply pricing moves with copper and stock levels rather than seasons. At $11.92 at Energy Avenue as of November 4, 2026, it is already near the bottom of its recent range, so waiting rarely helps.
Where is the Hubbell HBL2310ST Locking Receptacle cheapest?
At Energy Avenue, for $11.92, 42% under what the other stores charge, as of our latest check.
Where can I buy the Hubbell HBL2310ST Locking Receptacle?
13 stores we checked sell it, including Walmart, Energy Avenue, Standard Electric Supply Co., Galco Industrial Electronics, eBay.
