These couplings are rated to 3500kg, and are referred to as electric couplings because they don’t directly operate trailer brakes on their own. They are often used with trailer brakes, however; both with actuator-driven hydraulic brakes, and with controller-driven electric brakes.
These couplings are an extremely strong and robust design and are designed for use with A-frame drawbars. The handbrake lever incorporated into them can be used for cable parking brakes, a stipulation for trailers over 2500kg.
There is an estimated 1-2 week delivery timeframe for Trailparts products.
