Description
The B&W ICON 2-5/16″ Gooseneck Coupler Lock (Part LKGN0215) provides patented, power-tool-resistant trailer security engineered specifically for 2-5/16″ Bulldog BX1 gooseneck couplers with a round inner tube. Engineered to counter modern, aggressive attack methods like cordless angle grinders and rotary cutting saws, this heavy-duty cast steel enclosure locks directly over the BX1 locking mechanism and round tube profile to eliminate unauthorized hitching and towing.
Key Features
- Precision BX1 Round Fitment: Custom-engineered specifically to fit the unique collar geometry of the 2-5/16″ Bulldog BX1 round tube gooseneck coupler.
- Patented Radial Fin Geometry: Advanced cast steel fin architecture designed 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: Tailored drop-over design slides cleanly into place over the BX1 head without messy chains, loose brackets, or vulnerable exposed padlocks.
The Bulldog BX1 series is the gold standard for heavy-duty commercial hotshotting, agricultural machinery hauling, and livestock transport due to its high capacity and distinctive positive-locking collar. However, standard gooseneck locks offer almost zero defense against modern battery-powered cutoff tools, which slice through ordinary mild steel pins in seconds. The B&W ICON LKGN0215 neutralizes this vulnerability by completely shielding the BX1 round coupler 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, ranch mud, and extreme field conditions. It provides total peace of mind whether your rig is parked at a remote job site, staged overnight at a freight terminal, or stored on the property.
