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 Feature Specification Part Number 614054PL Rating (ATM) 2,000 kg Coupling Type Mechanical override/braked coupling Tow Ball Size Standard 50 mm Mounting Pattern 4‑hole: 182.5 mm × 55 mm; holes = 13.5 mm Finish Zinc-plated; corrosion-resistant Brake Lever Not included (mech/hydro override style) Compliance ADR approved / AS4177.3 standard 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
