Rhino USA 2" Trailer Coupler Lock Kit — Powder-Coated Steel, Keyed-Alike Security

Rhino USA's 2" Trailer Coupler Lock Kit secures 2-inch A-frame couplers with a rugged, powder-coated steel lock and matching latch lock to deter theft and weather damage.

Built for boat trailers, RVs, toy haulers and campers, this two-piece kit combines a tamper-resistant coupler lock and a keyed-alike latch lock so you only need one key for both. The steel body and durable powder-coat finish protect against rust and rough outdoor conditions, while the precise fit is designed for common 2" coupler sizes.

How does this lock fit different 2" couplers?

The kit is engineered to accommodate most 2" A-frame couplers, including 50x50 and 50x60 styles. Measure the coupler lip to confirm compatibility before purchase.

• Fits 2" A-frame, 50x50, and 50x60 couplers
• Maximum lip width: 3-3/4"
• Maximum lip height: 5/16"
• Designed to clamp securely around common trailer coupler shapes

What weather protection and materials does the lock offer?

The lock uses heavy-duty steel construction with a powder-coated exterior to resist corrosion and surface wear from sun, rain, and salt air. The finish extends the hardware’s usable life and keeps moving parts operating smoothly.

• Powder-coated steel body for rust resistance
• Sealed keyway and sturdy locking mechanism
• Durable under long-term outdoor storage conditions

Will the keyed-alike feature simplify daily use?

Yes — both the coupler lock and the latch lock are keyed alike so a single key operates the entire kit. Two matching keys are included, making one-handed removal quick when hitching or unhitching.

• One key opens both locks for convenience
• Two identical keys included for backups or shared use
• Reduces key clutter and speeds hookup routines

Rhino USA backs this kit with a real lifetime replacement policy and USA-based customer support. If you encounter defects or problems, the company will replace the unit or arrange a refund to ensure satisfaction.

• Lifetime replacement guarantee
• American-owned, family-operated customer support
• Easy claims process for replacements or refunds
