Adjustable railing kit quickly transforms your Thule Caprock roof platform into a versatile cargo basket.

Tested to the limit

At the Thule Test Center in Hillerstorp, Sweden, products go through extreme testing. Our roof rack systems are designed to carry your gear and fit your car as safely and securely as possible. Below are just a few examples of the many tests conducted.

Crash tests

We conduct multiple crash tests at different speeds and weights to ensure the complete roof rack system transports your gear safely and protects the vehicle from damage.

Wear and tear simulations

Specialized tests that are used to evaluate the roof rack systems over time, to assess their durability and long-term performance.

Exposure tests

To evaluate the performance of roof rack systems under conditions that might be encountered during use, we expose them to extreme heat, cold, damp, sunlight and chemicals.
