Description
The B&W ICON 3″ Gooseneck Coupler Lock (Part LKGN0300) delivers patented, power-tool-resistant trailer security engineered specifically for massive 3″ ball gooseneck couplers from Ram. Purpose-built to stop modern cordless angle grinders and rotary cutting saws, this heavy-duty cast steel vault encapsulates the oversized 3″ coupler socket and latching mechanism, completely denying thieves the clearance, leverage, or physical access required to tow away your heaviest rigs.
Key Features
- Precision 3″ Gooseneck Fitment: Custom-cast specifically to fit 3″ ball commercial gooseneck couplers manufactured by Ram.
- Patented Radial Fin Geometry: Advanced cast steel fin architecture designed to bind cutting discs, disrupt grinder attack angles, and rapidly wear down abrasive 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 depleting multiple high-output battery packs.
- 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 deterrent 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 Latching: Tailored drop-over design installs cleanly over the heavy-duty 3″ coupler head without messy chains, loose brackets, or vulnerable exposed padlocks.
Trailers fitted with 3″ ball gooseneck couplers represent the highest gross vehicle weight ratings in the industry—carrying multi-ton construction equipment, massive agricultural implements, and severe-duty commercial payloads. Because of the extreme value of these rigs, they are prime targets for organized theft operations armed with portable cutoff tools. Standard padlocks and collar pins offer zero defense against cordless angle grinders. The B&W ICON LKGN0300 provides the ultimate heavy-duty defense, locking down your 3″ Ram coupler inside blade-binding, heat-treated steel that turns theft attempts into noisy, battery-draining failures.
Designed for severe commercial, oilfield, agricultural, and fleet environments, the multi-stage protective coating and sealed internal tumbler resist rust, corrosion, and seized mechanisms through harsh winters, mud, and extreme job site conditions. It delivers uncompromised peace of mind whether your trailer is left unattended overnight at an active project site or staged long-term in an equipment yard.
