B&W ICON® 2-5/16" Gooseneck Lock for Round Cast (Bulldog/Curt) Couplers - LKGN0213

The B&W ICON 2-5/16" Round Cast Gooseneck Coupler Lock (Part #LKGN0213) delivers patented, power-tool-resistant security engineered specifically for 2-5/16" round cast head gooseneck couplers from top manufacturers including Bulldog and Curt. Built to stop aggressive attack methods like cordless angle grinders and rotary cutting saws, this heavy-duty cast steel enclosure envelops the cast coupler head and latch assembly, completely blocking unauthorized hitching and towing.

Key Features

• Precision Cast Gooseneck Fitment: Custom-cast specifically to fit 2-5/16" round cast gooseneck couplers manufactured by Bulldog and Curt.
• Patented Radial Fin Geometry: Advanced cast steel fin ribs engineered to bind cutting discs, disrupt attack angles, and rapidly wear down abrasive angle grinder wheels on contact.
• Proven Power-Tool Resistance: Engineered and independently tested to withstand continuous angle grinder attacks for over 90 minutes, destroying cutting discs and exhausting multiple tool batteries.
• Pick & Drill-Resistant Core: High-security disc-detainer locking cylinder recessed deep inside the solid casting, eliminating vulnerabilities to bump keys, traditional picks, and direct drilling.
• Over 20 Pounds of Hardened Cast Steel: Immense solid alloy construction serves as a heavy-duty physical barrier and an unmistakable visual warning across equipment yards, ranch lots, and jobsites.
• Dual-Layer Weather Protection: Automotive-grade E-coat primer beneath an industrial UV-resistant powder coat finish, complete with internal watertight seals to defend against rain, mud, road salt, and corrosive grime.
• Quick & Secure Operation: Precision-contoured drop-over design installs cleanly over the coupler base without messy chains, loose brackets, or vulnerable exposed padlocks.

Round cast gooseneck couplers from Bulldog and Curt are standard equipment on heavy-duty commercial trailers, livestock haulers, and equipment transports. However, standard gooseneck locks offer almost zero defense against modern battery-powered cutoff tools, which slice through ordinary mild steel in seconds. The B&W ICON LKGN0213 eliminates this vulnerability by completely shielding the round cast head inside blade-binding, heat-treated steel that turns theft attempts into noisy, battery-draining failures.

Engineered for demanding commercial, agricultural, and fleet applications, the multi-stage protective coating and sealed internal tumbler resist rust, corrosion, and seized mechanisms through harsh winters, farm mud, and extreme field conditions. It provides uncompromised peace of mind whether your rig is parked at a remote job site, staged overnight at a freight terminal, or stored on the ranch.
