AL‑KO 2,000 kg Braked Override Coupling – 50 mm Ball | 4‑Hole Mount Standard

Overview

Designed for trailers up to 2,000 kg, the AL‑KO 614054PL is a mechanical override (or over‑run) coupling engineered for both mechanical and hydraulic brake systems. Compatible with standard 50 mm tow balls, it features a 4-hole mounting plate for secure attachment and a zinc‑plated finish to resist corrosion.

As your tow vehicle decelerates, braking force transfers through the coupling shaft to actuate trailer brakes—either mechanically or hydraulically. Fully ADR-compliant, it’s a safe and effective solution for brake-equipped trailers under 2 t. 

 Key Features

• Rated to 2,000 kg (ATM) — suitable for electric or hydraulic brake trailers

• Mechanical override action—no need for hydraulic plumbing if mech‑braked setup used

• Zinc-plated corrosion protection for marine or road use

• Standard 50 mm tow ball interface

• 4-hole mounting plate (182.5 mm × 55 mm spacing; hole diameter 13.5 mm) 

• No external brake lever required

• Fully ADR & AS4177.3-compliant for legal use in Australia

• Optional hydraulic conversion kit (Part 610941) or mechanical brake plate (Part 614051) available to match braking setup 

 Technical Specifications

 Applications

This coupling is ideal for:

• Tandem or dual‑axle trailers fitted with mechanical or hydraulic brakes

• Caravans, camping trailers, utility trailers requiring override braking under 2 t

• Retrofits or new builds that need ADR-compliant brake coupling

• Setups where simplicity, reliability, and legal compliance matter
