Trailer anti-theft device for car and utility trailers
Effectively protect trailers against theft
Coupling locks and wheel clamps for different trailers and parking situations
A trailer anti-theft device makes it harder to couple or move your trailer without authorisation. Coupling locks, protective covers and wheel clamps secure different points of attack. The best solution for you depends on your coupling, parking location, and your required level of security.
A coupling lock is fitted directly to the coupling head. It's particularly suitable for short stops or if you regularly change parking locations. Some models can remain mounted even when the trailer is coupled. Always check the details on the relevant product page.
Protective covers are also fitted to the coupling on the drawbar. They are available in various security levels. Compact designs are easy to handle. More robust models include additional drilling protection or meet the demands of international security certifications.
The AL-KO PROSAFE wheel clamp blocks the trailer wheel. A special wheel bolt supplied remains permanently attached to the vehicle after an initial installation. The wheel clamp is suitable for caravans and utility trailers.
Overview of trailer anti-theft devices
- Coupling locks block the coupling mechanism and prevent unauthorised hitching or uncoupling.
- Protective covers enclose the coupling head and, depending on the design, also protect against drilling or removal.
- Wheel clamps block a wheel, preventing the trailer from being towed or rolled away.
- A Safety Ball fills the ball socket of uncoupled trailers and complements the coupling lock.
- Several visible security devices increase the time and effort required to attempt theft.
Which trailer anti-theft device fits which situation?
- Brief stop en route: A quickly fitted coupling lock makes it harder to uncouple without authorisation.
- Parking on your own property: A coupling lock with Safety Ball protects the coupling head of the uncoupled trailer.
- Longer standing periods: A wheel clamp blocks the wheel and provides a highly visible mechanical barrier.
- High-value trailer: Combine a coupling lock and wheel clamp to cover several points of attack.
- Trailers with AK 161 or AK 270: The Safety AK 161/AK 270 is specially designed for these couplings.
- Other coupling systems: Before purchasing, check the product designation, coupling type, diameter and installation situation.
Frequently asked questions about trailer anti-theft devices
Secure at least the coupling head with a suitable lock. For longer standing times, a wheel clamp is also recommended. A well-lit and protected parking space complements the mechanical precautions.
The best device matches the coupling and type of parking exactly. For the highest level of protection, combine a coupling lock and wheel clamp. No mechanical lock can ever completely prevent theft.
