Top 7 Hitchlocks Every Caravan Owner Needs

A hitchlock is one of the simplest, most visible ways to make a caravan a harder target. The Heavy Duty Alko 3004 Hitchlock is built around a 4mm steel body engineered in the UK, and it's tested to standards that exceed both Sold Secure Gold and SCM MP03 — two of the toughest independent benchmarks a hitchlock can carry.

What it's compatible with

This hitchlock is designed for Alko, AKS 2004 and AKS coupling systems, fitting directly over the coupling head to physically prevent it being connected to a tow ball.

Why the certification matters

Sold Secure Gold and SCM MP03 approval both involve independent attack testing, not just a manufacturer's own claims. A lock carrying both gives you a reasonable degree of confidence it's been through genuine scrutiny, rather than relying on looks alone.

Using it well

Like any hitchlock, it works best as part of a routine: fit it every time the caravan is left unattended, whether that's on the drive, in storage, or on a pitch, and keep it clean and free of grit so the mechanism keeps operating smoothly.
