AL-KO Kober Ball Coupler Mono 100mm 2,600kg

Provide controlled overrun braking performance and rigid structural towing support for medium-to-heavy commercial trailers, horseboxes, and touring caravans with the AL-KO Kober Ball Coupler Mono 100mm 2,600kg, distributed by Burquip. Precision-engineered by AL-KO Kober (Model 251S series), this heavy-duty mechanical overrun device is built to mount directly onto 100 mm square central drawbars (Mono straight-pole chassis layout), delivering proportional deceleration for trailers with a gross vehicle weight ranging from 1,500 kg up to 2,600 kg.

Key Features & Benefits:

• 1,500 kg to 2,600 kg Braked Capacity: Calibrated to actuate overrun braking systems smoothly and proportionally across single- or tandem-axle trailers without surging or pushing the towing vehicle.

• Mono 100 mm Square Chassis Mount: Engineered to sleeve directly over 100 mm square hollow section (SHS) central drawbars, ensuring rigid mechanical alignment for single-pole drawbar architectures.

• Integrated Hydraulic Overrun Damper: Features an internal, high-efficiency hydraulic shock absorber that softens stop-start transitions, preventing harsh jerking and brake snatch during sudden deceleration.

• Standard 50 mm Ball Coupling Head: Equipped with a precision-engineered cast ball hitch head compatible with standard 50 mm tow balls, featuring an ergonomic latching handle with a secondary safety lock to prevent accidental uncoupling.

• Spring-Assisted Over-Centre Handbrake: Features a heavy-duty mechanical parking brake lever that provides positive holding force to secure trailer brakes when parked on slopes or unhitched in storage.

• Integrated Breakaway Cable System: Fitted with a dedicated breakaway cable attachment point that automatically triggers the trailer brakes if accidental separation occurs during transit.

• Corrosion-Resistant Heavy-Gauge Construction: Fabricated from high-tensile cast and pressed steel treated with protective zinc galvanising to withstand continuous road spray, mud immersion, and stone chipping.
