AMPLock 2 5/16" Trailer Coupler Lock — Heavy-Duty Rust-Resistant Push-and-Lock for RVs and Trailers

AMPLock U-BRP2516 is a heavy-duty push-and-lock trailer coupler lock engineered to secure 2 5/16" straight-lip couplers against theft and unwanted movement while resisting rust for long-term outdoor use.

Whether you store a travel trailer, boat trailer, or utility trailer outside or routinely hitch and unhitch on the road, the AMPLock U-BRP2516 is made to be a simple, durable theft-deterrent. It replaces fiddly hitch-pin solutions with a fast push-and-lock action and a robust build rated for repeated use. The unit’s finish and material selection reduce corrosion, giving you dependable protection season after season without frequent upkeep.

How does the U-BRP2516 attach to a 2 5/16" coupler?

The lock is machined to match the dimensions of standard 2 5/16" straight-lip couplers so it sits flush and resists wobble. Installation is a one-step push until it engages; no complex tools or alignment procedures are required. When locked, it bridges the coupler opening to prevent the ball or hitch from seating properly, blocking unauthorized hookups.

• Precise 2 5/16" fit suited for straight-lip trailer couplers
• Push-and-lock action for quick, tool-free installation
• Locks over the coupler to prevent hitch seating and removal

What makes this lock durable for outdoor, long-term use?

The U-BRP2516 is constructed from high-strength materials chosen to resist impact and tampering while maintaining structural integrity during heavy use. A rust-resistant finish shields exposed surfaces from moisture and road salts so the lock stays functional through wet seasons. The combination of strength and corrosion resistance reduces the need for frequent maintenance or replacement.

• High-strength metal core resists forced entry attempts
• Weatherproof finish reduces corrosion in outdoor conditions
• Built to withstand repeated coupling cycles without deforming

How does the fast push-and-lock system benefit daily trailer use?

By eliminating pins, clips, or multi-step procedures, the push-and-lock design saves time during hookups and storage. This is helpful for frequent travelers and service professionals who handle trailers routinely. The mechanism locks securely with a positive tactile engagement so you can verify it’s set without trial-and-error.

• Immediate engagement for fast securing at campsites and storage yards
• Reduces fumbling in low-light or cold-weather environments
• Reliable tactile feedback confirms a secure lock every time

Will this work across different trailer types and accessories?

The U-BRP2516 is optimized for 2 5/16" straight-lip couplers, commonly found on travel trailers, larger cargo trailers, and many RV setups. It integrates cleanly into configurations that need a trailer tongue lock or hitch pin replacement without interfering with standard towing hardware. For other coupler styles or sizes, verify measurements before purchase to ensure a precise match.

• Compatible with most travel trailers, cargo trailers, and RV couplers of the specified size
• Functions as a hitch lock alternative without altering factory components
• Not suitable for couplers of different diameters or non-straight-lip designs

Who is this for: The AMPLock U-BRP2516 suits owners of trailers and RVs with standard 2 5/16" straight-lip couplers who want a fast, low-maintenance security solution. It’s ideal for campers, contractors, fleet managers, and boat owners who store equipment outdoors or frequently hitch and unhitch. If you need a rugged, weatherproof coupler lock that installs instantly and resists corrosion, this model offers practical protection without complicated installation.
