A trailer is only as reliable as its maintenance and security. Whether you want to protect your vehicle from thieves, need additional storage space for straps on the drawbar, or are looking for tools for regular servicing – the right accessories save time, money, and hassle. At trailer.one, you will find a handpicked selection of useful helpers for daily use and professional workshops.

Anti-Theft Devices: Security for Your Trailer

Don't give thieves a chance. We stock mechanical locking systems for both coupled and uncoupled trailers. Our range includes:

• Hitch Box Locks & Insert Locks: Block the coupling mechanism in an instant and prevent unauthorized towing.
• Safety Balls & Premium Coupling Locks: The perfect upgrade for modern stabilizer couplings (e.g., from AL-KO or Knott).
• Wheel Clamps: High-visibility and heavy-duty deterrence directly on the wheel, ideal for long-term outdoor parking.

Toolboxes & Drawbar Boxes: Tidiness on the Chassis

Where to keep ratchet straps, tools, and nets? Our splash-proof storage boxes and drawbar toolboxes, made of heavy-duty plastic or robust aluminium chequer plate, can be easily mounted on the chassis or directly onto the V-drawbar. This keeps your accessories exactly where you need them – securely locked and dry.

Workshop Equipment, Diagnostic Tools & Maintenance

To ensure your trailer runs smoothly, we provide professional testing and maintenance products:

• Lighting Testers & Diagnostic Kits: For fast troubleshooting on 7-pin or 13-pin electrical systems without needing a towing vehicle.
• Specialized Tools: For adjusting brakes, replacing wheel bearings, or installing suspension components.
• Lubricants & Corrosion Protection: Universal greases for the overrun coupling and zinc sprays to touch up scratches on the galvanized frame.

Look out for our proven "Trusted Aftermarket Product" seal to get field-tested accessories and tools in industrial quality at a fair price.
