AL-KO lock for square drawbar coupling

The mechanism that allows you to attach a trailer or other towing device to a car towbar is a so-called lock. It consists of two main structural elements:

1. attachment to the drawbar of the trailer hitch;
2. attachment of the coupling mechanism to the towbar.

Features of the locking hitch

When choosing a lock, you should pay attention to a number of characteristics that will make the device ideal and work perfectly.

• The shape and diameter of the drawbar (round, square).
• Matching the load capacity of the lock, drawbar, towing device, and vehicle.
• The material of manufacture must be steel, which ensures reliable and durable use.
• Anti-corrosion treatment will protect against damage and rapid damage as a result of mechanical damage by stones or similar objects, moisture and dirt.

Another important criterion is the brand that meets the standards and provides a guarantee of performance. The AL-KO brand is a German manufacturer that has gained worldwide recognition and millions of satisfied users over decades of operation.

Everyone who has a trailer in use needs to buy a trailer locking device, as it reliably fixes and guarantees the strength of the fastening during the transportation of materials by trailer.
