Top 7 Stabilisers & Bumper Protectors Every Caravan Owner Needs

The Milenco Stabiliser Anti-Theft Nuts protect a specific weak point on many caravans: the bolts holding the stabiliser hitch in place, which can otherwise be removed with an ordinary spanner.

How they work

Made from stainless steel, these are shear-head security nuts — tighten them until the outer head snaps off, and what's left is a tamper-resistant cone that can't be undone with standard tools. If removal is ever needed, it requires specialist methods such as drilling or an extractor.

Fitting

They fit in place of the standard nuts on your stabiliser fixings using ordinary tools, and are tightened firmly until the head shears off. Milenco notes they're used widely by caravan dealers on display units, and recommends checking the thread size and quantity needed for your specific stabiliser model before ordering, then cleaning the threads and applying the correct torque during installation.

Where they help

They're a simple, discreet way to add security to caravans left on display, in storage, or pitched for extended periods, without changing how the stabiliser itself works.
