Description
The B&W ICON 2-5/16″ Sleeve Lock Coupler Lock (Part LKBP0204) provides patented, power-tool-resistant trailer security engineered specifically for 2-5/16″ collar-lok and sleeve-lock style cast couplers from leading manufacturers including Bulldog and Ram. Purpose-built to defeat high-threat theft methods like cordless angle grinders and cutoff wheels, this ultra-rugged cast steel vault slides over the collar mechanism and ball pocket to deny thieves the leverage, clearance, and access needed to hitch up and drive off.
Key Features
- Precision Sleeve Lock Fitment: Custom-engineered specifically to fit heavy-duty 2-5/16″ sleeve-lock and collar-lok cast couplers manufactured by Bulldog and Ram.
- Patented Radial Fin Geometry: Advanced exterior fin ribs designed to bind high-speed cutting blades, disrupt grinder attack angles, and rapidly wear down abrasive discs.
- Proven Power-Tool Resistance: Built and tested to withstand continuous angle grinder attacks for over 90 minutes, chewing through multiple blades and exhausting high-capacity tool batteries.
- Pick & Drill-Resistant Core: High-security disc-detainer locking cylinder recessed deep inside the solid casting, eliminating vulnerabilities to drill bits, bump keys, and lock-picking tools.
- 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 locks down in seconds without messy chains, loose brackets, or vulnerable exposed padlocks.
Sleeve-lock couplers are widely favored for heavy equipment haulers, livestock trailers, and commercial cargo transports due to their robust positive-locking action. However, standard tongue locks provide zero defense against modern battery-powered angle grinders, which can cut through typical locking pins in seconds. The B&W ICON LKBP0204 eliminates this vulnerability by completely shielding the collar and latch inside blade-binding, heat-treated steel that turns theft attempts into noisy, time-draining failures.
Built for demanding commercial, agricultural, and fleet applications, the multi-stage protective finish and sealed internal tumbler resist corrosion, seizing, and road grime buildup season after season. It delivers uncompromising security whether your trailer is left unattended overnight at a remote project site or parked long-term in an equipment yard.
