Securing Transportable Accommodation: Strategies for Safeguarding Caravans and Similar Trailer Types

In today's world, securing your trailer is of utmost importance to prevent unauthorised coupling or disconnection, especially for heavy trailers such as caravans and motorhomes. Here's a roundup of manufacturers and suppliers offering specialist box locks (also known as security balls, metal hitch locks, or kingpin locks) for trailers.

Manufacturers and Suppliers

What Makes a Good Hitch Lock?

Steel Strength & Shape: Thick, hardened steel rods or plates make forced entry attempts more difficult.
Weather Resistance: Rust-resistant materials and special coatings protect against corrosion.
Locking Mechanism: High-quality locking systems, often with double locking, prevent picking.
Compatibility: Does the lock fit the specific hitch type and the hitch diameter?

Common Applications

Heavy Goods Vehicle/Trailer Hitch (Kingpin, Ball)
Caravan Hitch (Ball hitch)
Caravan and Boat Trailers

Buying Guide

Tip: Look at the reviews (especially theft resistance and weather resistance) and pay attention to TÜV and VdS certifications. For the highest security level, a lock with a "screw-on closure" instead of just a locking mechanism is recommended.

Online Purchasing: Shops like Amazon, eBay, Conrad, Reiff, eTrailer and specialised commercial vehicle dealers offer a wide range of options. For commercial users, suppliers like Butterfly Network or Bordnetz Service are interesting, as they also offer custom solutions.

Additional Security Measures

The Nemesis Ultra wheel clamp from manufacturer Fullstop is a wheel clamp option that can secure caravan wheels against driving away, suitable for rims with a size of 13 to 16 inches.
A hidden GPS tracker can provide information about the location of the trailer or caravan if other anti-theft measures are bypassed by thieves.
The Triburg box lock is suitable for both coupled and uncoupled trailers and fits common ball coupling sizes within certain height and width dimensions.
The Milenco caravan anti-theft device is a support lock that blocks the turn-out supports and prevents the caravan from being jacked up.
The AL-KO Safety Compact anti-theft device is made of high-strength steel and provides protection for specific AL-KO stabilizer and ball couplings.

In Conclusion

If you're specifically looking for a lock that denies unauthorised coupling or disconnection of your trailer, I recommend ABUS, Thule, Master Lock and JOST as the first points of call. For special applications (such as very heavy caravans), a look at the offerings from Kryptonite and Curt may be worthwhile.

When in Doubt: When searching, use specific terms like "ball hitch lock", "kingpin lock" or "trailer hitch closure" and pay attention to the exact fit for your trailer (ball diameter, hitch width, type).

If you need a specific product for a particular trailer hitch, please let me know the exact details (such as ball diameter, manufacturer of the hitch), and I can give you a targeted recommendation!
