Bryant 7 Series Flanged Locking Receptacle

Bryant's 7 Series Flanged Locking Receptacle line spans 26 model configurations, from 71020ER through 72330ER, engineered for secure, panel-mounted power connections across industrial and commercial facilities. Each device in this family uses Bryant's twist-lock blade pattern to keep a mating plug firmly seated, reducing the risk of accidental disconnection from vibration or accidental pull-out during operation. The flanged body mounts directly to equipment enclosures, panels, or bulkheads, giving installers a fixed, dedicated outlet location rather than a portable connector. Locking devices of this type are commonly specified where a power connection must stay engaged under load, such as machinery, portable equipment stations, and temporary power setups.

Key Features

  • Locking Configuration: The family covers 26 Model options (71020ER through 72330ER), each built around a specific NEMA locking receptacle pattern to match the required twist-lock plug.
  • Twist-Lock Engagement: As L-series devices, these receptacles use a twist-lock blade engagement to resist vibration and pull-out once the mating plug is seated.
  • Flanged Mounting: Flange-style body allows direct panel, enclosure, or bulkhead mounting for a fixed, permanent outlet installation rather than a portable connection.
  • 7 Series Platform: Part of Bryant's 7 Series wiring device line, designed for consistent fit and function across compatible Bryant locking devices.
  • Receptacle Style Outlet: Configured as a receptacle (R) outlet to accept the corresponding locking plug for a positive electrical connection.
  • Model Range: Choose from 26 model numbers (71020ER, 71030ER, 71120ER, and others through 72330ER) to match the specific locking pattern required for a given project.

Why Bryant?

Bryant has long supplied electrical contractors and facility engineers with wiring devices built for dependable field performance. The 7 Series Flanged Locking Receptacle line continues that focus, pairing a twist-lock platform with a flange-mount design suited to permanent industrial and commercial power connections across its 26 model configurations. Choosing a twist-lock configuration helps ensure connections stay seated under load instead of working loose over time. Specifying Bryant means standardizing on a locking device family engineered for consistent, code-compliant performance across a facility.

Bryant 71020ER – Frequently Asked Questions

1) What is the difference between a flanged locking receptacle and a flush mount one?
Bryant's 7 Series locking receptacles are flanged devices, meaning the body mounts through a hole in an equipment enclosure, panel, or bulkhead with the flange sitting on the outside surface. That gives you a fixed outlet on machinery or a power distribution panel instead of a wall box device. If you are feeding a standard wall or floor box in a finished space, a flush mount locking receptacle such as the Leviton 2420 or Leviton 2510 is the right style instead.
2) Which NEMA locking configurations does the Bryant 7 Series flanged receptacle come in?
26 configurations, running L10 through L23 in both 20A and 30A versions: L10-20R, L10-30R, L11-20R, L11-30R, L12-20R, L12-30R, L13-30R, L14-20R, L14-30R, L15-20R, L15-30R, L16-20R, L16-30R, L17-30R, L18-20R, L18-30R, L19-20R, L19-30R, L20-20R, L20-30R, L21-20R, L21-30R, L22-20R, L22-30R, L23-20R and L23-30R. Model numbers follow the pattern directly, so an L14-30R is model 71430ER and an L21-30R is 72130ER. Pick the configuration that matches the plug on the equipment, since locking blade patterns are not interchangeable between NEMA designations.
3) I need a 30A 125/250V twist-lock outlet for a generator inlet on a panel. Which Bryant model?
That is a NEMA L14-30R, which is Bryant model 71430ER in the 7 Series flanged line. L14-30 is the 3-pole, 4-wire 125/250V 30A locking pattern used on most portable generator cordsets. If your generator cord is 20A instead, use 71420ER for the L14-20R pattern.
4) Will a 20 amp twist-lock plug fit a 30 amp Bryant locking receptacle of the same NEMA family?
No. An L14-20 plug will not enter an L14-30R receptacle, and the reverse is also true. NEMA locking blade patterns differ by amperage as well as by voltage and pole count, which is the point of the system. Order 71420ER for 20A L14 loads and 71430ER for 30A L14 loads, matched to the cord cap you actually have.
5) Why use a twist-lock receptacle instead of a straight blade one on machinery?
The 7 Series uses a twist-lock blade engagement, so once the plug is inserted and rotated it stays mechanically captive. On machinery, portable equipment stations, and temporary power that matters because vibration or a pull on the cord will not drop the connection the way it can with a straight blade device. It also means the plug and receptacle must share the same NEMA locking designation, which prevents someone plugging a 480V load into a 250V outlet.
6) Do I need a three-phase locking receptacle or a single-phase one?
It depends on the load, and the 7 Series covers both. Single-phase patterns in the range include L14-20R and L14-30R (125/250V) and L15 is three-phase 250V. The L16, L17, L21, L22 and L23 designations in the family are three-phase configurations at higher voltages, with L21 being 120/208V wye four-pole. Match the designation stamped on the equipment cord cap rather than working from voltage alone, because several patterns share a voltage but differ in pole and wire count.
7) I have a 277/480V four-wire load. Is there a Bryant 7 Series option, or should I look at Leviton?
For 480V wye four-pole service, the 7 Series flanged range includes L22-20R (72220ER) and L22-30R (72230ER). If you need a flush mount device instead of a flanged one for that voltage class, the Leviton 2450 is an industrial grade 4-wire 4-pole locking receptacle rated 277/480V wye at 20A.
8) For a machine shop where the outlet takes impact and chemical exposure, how do the options compare?
The Bryant 7 Series flanged locking receptacles mount directly to an enclosure or bulkhead, which puts the device body behind the panel face and fixes it in place against vibration and pull-out. If a flush mount device suits the opening better, the Leviton 2420 is an industrial grade locking receptacle described as impact- and chemical-resistant. The Eaton 7540 and Eaton L14-20 locking receptacles are commercial grade.
9) Is the Bryant 7 Series a good choice for standardizing locking outlets across a facility?
That is the main argument for it. All 26 configurations sit on the same 7 Series flanged platform, so panel cutouts, mounting, and stocking practice stay consistent while the blade pattern changes with the circuit. Model numbers are readable too, with the NEMA family and amperage embedded (71020ER for L10-20R through 72330ER for L23-30R), which makes reordering the right unit straightforward for MRO storerooms.
