• PERFECT FIT FOR 2‑5/16″ COUPLERS: Before you park your boat, RV, or cargo trailer for the night, make sure your lock fits. This coupler lock is engineered exclusively for 2‑5/16‑inch couplers, 🚫not for 2 inch. A snug, gap‑free fit means thieves can’t wiggle or pry it loose. Always double‑check your coupler size before buying, so you get maximum theft protection right out of the box.
• HIGH-SECURITY BRASS CORE: Worried about someone picking your lock or using a bump key? Inside this 2‑5/16 trailer lock lies a premium brass core that resists picking, drilling, and tampering. The custom hockey puck shape adds an extra layer of security by shielding the locking mechanism from bolt cutters. Three included keys give you a backup – keep one on your truck, one at home, and one in your toolbox.
• HEAVY‑DUTY HARDENED STEEL: Imagine a thief with a crowbar or a grinder going after your trailer hitch. With this trailer hitch coupler lock made from reinforced hardened steel, they’ll get nowhere. It’s built to resist cutting, prying, and brute‑force impacts – whether your trailer is parked at a remote trailhead, a storage lot, or a dimly lit gas station. Your trailer stays yours.
• ALL‑WEATHER PROTECTION: Leaving your trailer outside all year? No problem. This coupler lock features a high‑quality coating that fights rust and corrosion through rain, snow, salt spray, and extreme heat. From frozen mountain passes to humid coastal marinas, it keeps unlocking smoothly and staying strong – season after season, without constant maintenance.
• SIMPLE INSTALLATION & QUICK REMOVAL: You shouldn’t need a mechanic’s license to lock up your trailer. This trailer tongue lock is designed for simple installation and quick removal – no complicated tools, no wrestling with pins. Just slide it on, lock it, and walk away with confidence. When you’re ready to hit the road, it comes off just as fast. Minimal effort, maximum peace of mind.
