Burquip Ball Coupler Delta 2,700kg With Anti-Sway Head 

Provide premium high-speed stability, sway suppression, and controlled overrun braking for heavy touring caravans, enclosed car transporters, and horseboxes with the Burquip Ball Coupler Delta 2,700kg With Anti-Sway Head. Combining a Delta (A-frame) mechanical overrun braking assembly with an integrated friction-pad stabiliser coupling head, this unit suppresses lateral trailer fishtailing (yaw) and vertical pitching movements before they reach the towing vehicle, while delivering proportional braking for gross trailer masses up to 2,700 kg.

Key Features & Benefits:

• Integrated Anti-Sway Friction Stabiliser: Utilises internal high-friction pads that compress directly against the 50 mm tow ball when the clamping handle is engaged, damping snaking, trailer sway, and pitching motions caused by crosswinds, passing heavy trucks, and road ruts.

• 2,700 kg Overrun Braking Capacity: Calibrated to actuate mechanical drum or disc brakes smoothly and proportionally for single- or tandem-axle trailers up to 2,700 kg GVM, preventing trailer shove and keeping stopping distances controlled.

• Delta (A-Frame) Chassis Geometry: Features an engineered Delta housing profile designed to bolt directly over converging A-frame drawbar beams, distributing towing and braking forces evenly into the chassis structure.

• Electronic Stabilisation Compatibility: Optimised for use alongside Electronic Trailer Stabilisation (ETS) systems for dual-layer mechanical and electronic sway mitigation.

• Integrated Hydraulic Overrun Damper: Fitted with an internal hydraulic shock absorber that softens push-pull transitions during stop-start driving, 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 the trailer brakes when parked on slopes or stored unhitched.

• Emergency Breakaway Protection: Pre-fitted with attachment points for an emergency breakaway cable, ensuring immediate, fail-safe brake engagement if accidental decoupling occurs in transit.

• Visual Wear & Latch Indicators: Integrated gauges allow operators to inspect friction pad thickness and verify complete, secure engagement over the tow ball before towing.
