Description
The B&W ICON 2-5/16″ Twist Latch Cast Coupler Lock (Part LKBP0209) provides patented, power-tool-resistant trailer security engineered specifically for 2-5/16″ cast couplers equipped with a twist-latch mechanism from Ram. Built to counter aggressive modern theft techniques like cordless angle grinders and rotary saws, this massive cast steel vault locks completely around the twist-latch assembly and ball socket to block unauthorized hookups and towing attempts.
Key Features
- Precision Twist Latch Fitment: Custom-cast specifically to fit 2-5/16″ heavy-duty cast couplers featuring the Ram twist-style latch assembly.
- Patented Radial Fin Geometry: Advanced cast steel fin architecture designed to bind cutting discs, disrupt attack angles, and rapidly chew through abrasive angle grinder wheels.
- Proven Power-Tool Resistance: Engineered and independently tested to withstand continuous angle grinder attacks for over 90 minutes, destroying blades and depleting 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 deterrent on staging yards 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 smoothly in seconds without messy chains, loose brackets, or vulnerable exposed padlocks.
Trailers fitted with Ram twist-latch cast couplers are standard across heavy equipment hauling, commercial landscaping, and commercial cargo transport. However, conventional coupler locks and padlocks offer virtually no resistance against portable cordless cutoff tools, which can bypass them in seconds. The B&W ICON LKBP0209 eliminates this vulnerability by completely shielding the twist latch and collar inside blade-binding, heat-treated steel that turns theft attempts into noisy, battery-draining failures.
Designed for demanding commercial and fleet environments, the multi-stage protective coating and sealed internal tumbler resist rust, corrosion, and seized mechanisms through harsh winters and extreme job site conditions. It delivers uncompromising security whether your trailer is left unattended overnight at an active project site or parked long-term in an equipment yard.
