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.

    Wheel clamp PROSAFE

    The wheel clamp blocks the wheel and prevents the trailer from being easily moved. A robust case makes transport and storage easier.

    Safety AK 161/AK 270 coupling lock

    The reinforced, hardened coupling lock fits to the coupling heads AK 161 and AK 270. It can be used both when parked and while driving.

    Protective covers Safety Compact, Plus and Premium

    The Safety Compact is the compact entry-level option. The Safety Plus adds a massive steel construction with a drilling protection feature. The Safety Premium offers the highest level of security in this product line.

    Safety Ball

    The Safety Ball fills the ball socket in uncoupled trailers. It is used together with a suitable coupling lock.

    ROBSTOP coupling locks

    ROBSTOP locks protect against unauthorised hitching or uncoupling and against removal of the coupling head. The suitable version depends on the fitted coupling model.

    SAFETY BOX K and SAFETY BOX XL-K

    The SAFETY BOX protects the coupling head against unauthorised hitching or uncoupling. The supplied stainless steel disc lock secures the device directly to the coupling head. It can also remain mounted while driving. With the SAFETY BOX K and the larger SAFETY BOX XL-K, you have options for common coupling heads. Before selection, check compatibility with your specific coupling model.

    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.
