Caravan Security: In-Depth Look at Caravan Wheelclamp (Original) C14 Sold Secure

The Caravan Wheelclamp (Original) C14 is UK-manufactured and has been a favourite among caravanners for over a decade, prized for its resistance to attack and straightforward fitting.

Certification

It's independently attack-tested and approved by the Dutch Road Research Institute TNO — one of Europe's most demanding test centres — and is approved to SCM MP03, the highest accredited standard for caravan security worldwide. It far exceeds the Sold Secure Gold standard, with a pick-proof lock built to resist sawing and freezing.

Build and fit

The locking mechanism has been re-engineered to make lining up and fitting the clamp quicker and easier than earlier versions. It suits both alloy and steel wheels, with a foam backing on the main body to protect alloys from scratching. The lock is brass rather than die-cast, with ten pins instead of the seven found in many cheaper locks, and the clamp body is case-hardened steel that resists hacksawing.

Sizing

This C14 size suits caravans with 14" and 15" single axle wheels — worth double-checking your wheel size and axle configuration against Milenco's size guide before ordering, since the wheelclamp range covers several different sizes.
