Milenco C13 Wheel clamp to fit 13" Single Axle or 14" Twin Axle: Features, Benefits and Installation

The Milenco C13 Wheel Clamp is a UK-manufactured caravan wheel clamp, sized to fit 13" single axle or 14" twin axle wheels — check your wheel size against Milenco's fitting guide before ordering, as sizing varies between the C13 and C14 versions. Caravan theft is a genuine risk in the UK: Metropolitan Police freedom-of-information data collected across 30 UK police forces recorded roughly 500–570 caravan thefts a year between 2020 and 2022. A visible, well-tested clamp is one of the simplest ways to make a caravan a harder target.

Independent testing

This clamp has been independently attack tested by the Dutch Road Research Institute (TNO), one of Europe's most demanding test centres, and is approved to SCM MP03 — the highest internationally accredited standard for caravan security. It's built to exceed the Sold Secure Gold standard, resisting sawing, freezing and picking attempts.

Build quality

Milenco uses a purpose-designed high-security lock rather than an off-the-shelf unit: it's brass rather than die-cast, with a ten-pin cylinder rather than the more common seven. The clamp body is case-hardened steel, which resists hacksawing, while remaining relatively light to carry and store.

Fit and protection

It suits both alloy and steel caravan wheels. A foam backing on the main body protects alloy rims from scuffing during fitting and removal, and the locking mechanism has been re-engineered from earlier Milenco clamps to make it quicker to line up and lock into place.

Choosing the right size

Milenco also offers a C14 version, sized for 14"–15" single axle wheels, so check your caravan's exact wheel size and axle configuration against the fitting details before ordering.
