Rhino USA Trailer Coupler Lock Kit 2-5/16in — Keyed-Alike Powder-Coated Anti-Theft Steel

Protect your trailer with a purpose-built lock set that fits common A-frame couplers and standard tongue latches. This Rhino USA kit combines a robust coupler lock and a matching pin latch lock, both finished to resist corrosion and backed by a lifetime replacement policy. The design focuses on simple installation, one-key operation, and long-term durability for boats, RVs, utility trailers, and work trailers parked at home, the job site, or in storage.

Which coupler sizes and designs will this lock fit?

The kit is engineered for 2-5/16" couplers and several compatible A-frame styles. It secures couplers with specific lip width and height limits and is not compatible with rolled-lip or underslung styles. Check measurements before ordering to ensure a correct fit.

• Fits 2-5/16" A-frame, 50x50, and 50x60 couplers
• Maximum lip width: 4-3/8"; maximum lip height: 5/16"
• Not suitable for rolled-lip or underslung coupler designs
• Includes pin lock sized for standard tongue latch holes

How does the kit resist weather and corrosion?

Both components receive a heavy powder-coat finish that helps block rust and extend service life in outdoor conditions. The steel construction provides core strength while the coating prevents moisture and road salt from rapidly degrading the surface. This treatment reduces maintenance and preserves a neat appearance.

• Durable powder-coated steel finish for corrosion resistance
• Sealed hardware minimizes water intrusion points
• Built to handle storage and regular outdoor exposure

What makes the keyed-alike feature useful?

The kit ships with both locks operating on the same key, eliminating the need to carry multiple keys when hitching or un-hitching your trailer. Two matching keys are included so you have a spare on hand. One-key convenience speeds routine use and reduces fumbling in low light or cramped spaces.

• Both locks open with the same key for single-key access
• Two matching keys included for backup
• Quick one-handed on/off operation when securing or releasing

What after-sale support and warranty are provided?

Rhino USA stands behind this lock kit with lifetime replacement coverage: if defects or failures occur, they will supply a replacement or refund to resolve the issue. The product also benefits from US-based customer service through a family-operated company for straightforward support and parts help.

• Lifetime replacement guarantee for peace of mind
• American-owned, family-run customer support
• Replacement or refund policy for defective items
