COOHAME Trailer Hitch Lock for 1-7/8 in, 2 in, 2-5/16 in Couplers — 2-Pack Red, Adjustable Heavy-Duty

Protecting your trailer when it’s hitched or parked starts with a reliable coupler lock. The COOHAME Trailer Hitch Lock 2-Pack includes two adjustable tongue locks finished in high-visibility red and built from durable steel and aluminum alloys. They’re engineered to fit the most common ball coupler sizes and to resist tampering, weather, and everyday wear so you can leave a trailer, boat, or camper with more confidence.

How does this lock fit different coupler sizes?

The locks use an adjustable internal mechanism that adapts to a range of ball coupler sockets so one model covers 1-7/8", 2", and 2-5/16" sizes. Turning the key expands or contracts the locking head, allowing a secure fit without needing multiple separate locks.

• Adjustable range covers the three most common ball diameters.
• One-turn key operation sets the lock position quickly and reliably.
• Works on RVs, boat trailers, utility trailers, and pickups.

What materials and construction resist theft and corrosion?

COOHAME combines heavy-duty steel and quality aluminum in the lock body to maximize strength while minimizing weight. The metal surfaces are treated to slow rust and corrosion, and the internal lock core is designed to reduce forced entry attempts.

• Hardened steel components deter cutting and prying.
• Aluminum elements resist environmental corrosion for longer life.
• Robust lock core requires full rotation to open, improving security over partial-turn designs.

How easy is installation and daily use?

Installation is straightforward: insert the locking head into the coupler socket, turn the key to expand the lock, then remove the key. The bright red finish makes the device visible at a glance so you and others can immediately spot that the trailer is secured.

• Quick on/off action saves time during hookups and storage.
• No special tools required—key-operated expansion locks the coupling.
• Compatible with most trailer types including boats, campers, and work trailers.

What makes the red color a practical choice?

The striking red finish serves as a visual deterrent: thieves are less likely to target a trailer that clearly displays anti-theft hardware. The color also helps owners spot their locked trailers easily on lots or driveways.

• High-visibility color discourages opportunistic theft.
• Makes checking security status fast during inspections.
• Stands out against common trailer finishes for easy identification.

Who is this for? The COOHAME Trailer Hitch Lock 2-Pack is suited for trailer owners who want simple, effective theft deterrence without carrying multiple size-specific locks. It’s ideal for boat owners, RV and camper users, tradespeople with utility trailers, and anyone who parks or stores trailers in shared or unsecured locations. The adjustable fit, weather-resistant materials, and visible red finish make it a practical choice for everyday protection and longer-term storage.
