Heavy Duty Alko 3004 Hitchlock SCM/SOLD SECURE: Features, Benefits and Installation

Caravan security often comes down to layering several deterrents, and the hitch is one of the most obvious points to protect. Metropolitan Police freedom-of-information data collected across 30 UK police forces recorded roughly 500–570 caravan thefts a year between 2020 and 2022, and an unsecured hitch makes towing a caravan away far easier for an opportunist.

The Heavy Duty Alko 3004 Hitchlock is built from 4mm steel, engineered in the UK, and fits Alko, AKS 2004 and AKS 3004 hitch systems.

Certification

It surpasses both the Sold Secure Gold and SCM MP03 standards, and Milenco states it has been tested to offer security levels 2.5 times stronger than former industry benchmarks.

Build and deterrent value

Beyond its mechanical resistance to attack, the lock's size and design work as a visual deterrent in their own right — a thief looking for an easy target is less likely to persist with a caravan that's visibly protected at the hitch as well as the wheel.
