Trailer Lock Fits 2 5/16 Inch Couplers, Secures Safety Chains Anti-Theft Ball Hitch Lock, Pry Resistant Heavy Duty Hitch Locks for RV, Cargo, Camper, Dump Trailer (Red) — Open-Box, 16% Off

FITMENT CHECK: Please verify your 2-5/16" trailer coupler matches the compatible designs displayed in the product photos prior to purchase to ensure a proper fit and optimal locking security.

DUAL-DEFENSE VAULT-SEAL: Most standard locks only guard the coupler itself, leaving exposed safety chains vulnerable to bolt cutters. The Boltly tongue lock secures both at the same time: simply slide the inner mechanism into your 2-5/16″ coupler, attach the safety chains to the built-in ball mount, and press down to lock. A single solid “clack” establishes a reinforced anti-theft barrier featuring minimized pry points and zero exposed chain gaps. Perfect for boat ramps, marina parking lots, dump trailers, cargo trailers, and overnight outdoor storage.

ARMOR-GRADE STEEL PROTECTION: Constructed with reinforced, heat-treated steel housing to withstand pry bars, bolt cutters, hammer strikes, and smash-and-grab thefts without easily cracking or deforming under heavy pressure. Tailored for dump trailers, equipment haulers, cargo units, travel trailers, and motorcycle carriers regularly exposed to gravel roads, construction sites, and high-risk parking areas. This heavy-duty build substantially increases cutting time, noise, and effort for potential thieves.

FORTRESS-GRADE SEALED BRASS CORE: The precision-machined solid brass cylinder is equipped with anti-pick grooves, hardened drill-resistant pins, and a completely sealed keyway designed to block out moisture, road salt, mud, and dust. Engineered to help deflect bump-key attacks, lock picking, and drilling methods frequently targeted at standard coupler locks. Ideal for RVs, boat trailers, utility haulers, and high-humidity or freezing outdoor climates where lock jamming typically occurs.

ELEMENT-PROOF ALL-WEATHER PERFORMANCE: Featuring a durable powder-coated exterior and a fully sealed locking core to fight off salt spray, rain, snow, mud, desert dust, UV radiation, and road grime in demanding outdoor environments. This Boltly hitch lock is built for marina launches, landfill trips, messy jobsites, freezing winters, and long-term parking, requiring minimal upkeep and ensuring smooth year-round functionality.

ONE-CLICK FAST LOCKING: The patented puck-style push-lock mechanism fastens your trailer in mere seconds with no loose pins, frustrating alignments, or stiff locking levers to deal with. Designed for quick daily operation during gas station stops, campground visits, marina unloading, busy work sites, and frequent trailer swaps. Comes complete with 2 heavy-duty keys so you can keep one in the truck, one in the garage, another in the glove box, and still have extras left over.
