Burquip Ball Coupler Mono 80x80 2,000kg

Deliver controlled overrun braking deceleration and rigid structural towing support for medium-duty commercial trailers, horseboxes, and touring caravans with the Burquip Ball Coupler Mono 2,000kg. Built around the KNOTT overrun braking system for straight central drawbars (Mono / single-pole chassis configurations), this mechanical overrun assembly sleeves directly over 80 × 80 mm square hollow sections (SHS). It integrates a hydraulic damper, handbrake lever, and positive-locking 50 mm ball coupling head to provide proportional braking deceleration for trailers with a gross vehicle weight ranging from 1,100 kg up to 2,000 kg.

Key Features & Benefits:

• 1,100 kg to 2,000 kg Braked Capacity: Calibrated for medium-duty single- and tandem-axle trailers with a Gross Vehicle Mass (GVM) up to 2,000 kg, actuating trailer brakes in proportion to tow vehicle deceleration without surging.

• Mono 80 × 80 mm Chassis Mount: Engineered to sleeve directly over 80 × 80 mm square central drawbars, ensuring rigid mechanical alignment for single-pole drawbar architectures.

• Standard 50 mm Ball Coupling Head: Equipped with a heavy-duty ball socket head (Socket Code: CBKBALL45) compatible with standard 50 mm tow balls, featuring an ergonomic latching handle to prevent accidental detachment.

• Internal Overrun Hydraulic Damper: Houses a heavy-duty hydraulic shock absorber within the sliding shaft to cushion push-pull transitions during stopping and accelerating, eliminating harsh jerking and brake snatch.

• Spring-Assisted Over-Centre Handbrake: Features an over-centre parking brake lever with a ratchet mechanism to mechanically lock trailer brakes when parked on steep inclines or stored unhitched.

• Emergency Breakaway Protection: Pre-fitted with attachment points for an emergency breakaway cable, ensuring immediate, fail-safe brake engagement if the trailer separates from the towing vehicle.

• 100 kg Static Vertical Load Rating: Certified to carry a maximum static nose weight of up to 100 kg at the coupling point.

• Durable Heavy-Duty Construction: High-tensile cast and fabricated steel body with protective anti-corrosion coating to withstand gravel road vibrations, road spray, and outdoor weathering.
