The first impression
Packaging and labeling
ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.
| Criterion | Remark | Score achieved* |
|---|---|---|
| Product protection | Carton is sturdy, product sufficiently protected | 100 points |
| Sustainability Packaging | Unnecessary packaging waste was avoided, items were packaged compactly, use of plastic | 80 points |

| Total | 93 points |
*The maximum score is 100 points
The Werkthor trailer lock arrived in the typical Amazon box. The box was undamaged and easy to open by removing the adhesive tape. The box contained the trailer lock with accessories packed in a product box. It also contained a business card with a brief introduction to Werkthor. The lock itself and the other accessories were wrapped in plastic film. The plastic film might not have been necessary, but it protects the product and accessories from dirt and scratches. In this case, the product was fully protected and the trailer lock was therefore in perfect condition.
The packaging of the trailer lock is partially recyclable. Unfortunately, the plastic is not recyclable, but the Amazon box is.
Overall, the Werkthor trailer lock makes a very good impression. The lock was not damaged and the package was in good condition.

After unpacking, five items were found on the workbench. In addition to the fob lock, there was a steel shackle, a cover cap, a padlock and two matching keys in the product packaging. There are no instructions for use. The contact information is given on the product box, only the hotline is missing. All in all, this is an exceptionally well thought-out and customer-friendly way of shipping a product.

The trailer lock is made of rustproof and weather-resistant steel without any annoying corners or edges. The box lock is not firmly connected by the hinge, but falls apart if it is not operated correctly. The steel bracket is also not firmly attached to the lock. However, this is the case with most rim locks and with a little practice it is not a problem.
Due to the high-quality materials used, we expect the lock to be extremely durable.
This is what our practical test showed

We enjoyed using the trailer lockduring the test. The lock is sturdy and can be easily attached to the towbar with a little practice. The fact that the trailer lock can be opened completely also has advantages when installing it, as you can simply place the two parts around the coupling without any additional problems. The locking bolt can be inserted quickly and easily, as can the lock supplied. The cap supplied as protection for the towbar is also a nice addition.
A simple and common trailer lock for theft protection for trailers of all kinds.
