Discover the Reliability of Hubbell's Marine-Grade Locking Receptacle

Engineered for demanding environments like marinas, boatyards, and coastal installations, this Hubbell duplex locking receptacle combines rugged durability with secure twist-lock performance. Its bright yellow nylon housing stands out for safety and quick identification, while the corrosion-resistant construction ensures long-term reliability even in salty air or humid conditions. Whether powering boat chargers, dockside tools, or RV hookups, this 15A 125V device prevents accidental unplugging, reducing downtime and hazards.

Unlike standard outlets, the L5-15R configuration locks plugs firmly in place, ideal for vibration-prone settings. The duplex design means two independent outlets in one compact unit, doubling your connectivity without extra space. UL and CSA approvals confirm it meets stringent safety standards for peace of mind.

Key Features That Set It Apart

• Twist-Lock Security: NEMA L5-15R design grips plugs tightly, resisting pulls and vibrations common in marine or industrial use.
• Corrosion-Resistant Build: Nylon body and plated contacts defy rust and chemicals, perfect for wet or salty atmospheres.
• Duplex Configuration: Two receptacles side-by-side for versatile power distribution in tight spaces.
• Compact and Lightweight: Measures just 3.28 x 1.7 x 1.17 inches and weighs only 4 oz, making installation straightforward.
• Yellow Color Coding: Enhances visibility in low-light or cluttered areas, aiding quick connections.
• 1-Phase, 2-Pole, 3-Wire Grounding: Safe and compliant for 125V applications up to 15 amps.

Why This Receptacle Excels in Harsh Conditions

In marine settings, ordinary outlets fail fast due to moisture and corrosion. This Hubbell model uses advanced materials like fiberglass-reinforced nylon, which flexes without cracking and maintains integrity over years of exposure. The flanged design allows flush mounting into panels or boxes, creating a professional, snag-free surface.

Users appreciate its reliability for high-stakes tasks—think keeping bilge pumps running or charging batteries without interruption. Compared to non-locking duplexes, it slashes the risk of power loss from jostled cords. For DIY boat owners or facility managers, it's a smart upgrade that pays off in reduced maintenance and enhanced safety.

Installation Tips for Optimal Performance

Proper setup maximizes this receptacle's lifespan. Always turn off power at the breaker before wiring. Use 14 AWG wire for 15A circuits, connecting hot to brass terminals, neutral to silver, and ground to green. Torque screws to spec (typically 12-14 in-lbs) to avoid loose connections. Mount in a NEMA 1 or 3R enclosure if outdoors, as it's not watertight. Test with a locking plug to confirm twist-lock engages smoothly.

Pro tip: Pair with Hubbell's matching plugs for a complete, color-coded system that simplifies inventory and matching.
