Eastern Canadian Petzl Pro Rep Van

I had an earlier version of this ski box which lasted over 20 years of 4 season service. I recently received a larger box which has proven to be a perfect size.

This box fell from 24th floor and survived.

I own this box (Force XT) and it served me well all the time. I live in Spain (Valencia) and these days, Spain is under a storm - trees are falling in the city. My flat is on the 24th floor. My box was kept on the balcony for the last months. Until yesterday... Yesterday, the wind was so strong, it lifted the box and sent it flying. Box flew over the building and landed on the street. It's hard to believe, but no one was hurt, no property was damaged. Luckily, people don't go out in the storm. The box basically fell 24 stores and landed as an airplane in the middle of the street. I thought the box would not survive. But appears it only has some dents and scratches. Two locking hitches cracked and I'm looking for a replacement now. So there you have my story. Thule makes great boxes.

Updated locking mechanism!

This is my second Thule rooftop carrier box. The first is still functional, yet failing slowly as the locking mechanism is failed on one side. I was skeptical to purchase a new carrier considering this design flaw on the older carrier. However, upon inspection of the mechanism on the new Force 3 I purchased, Thule has done a good job beefing up the locking mechanism and removing the design flaw from previous versions.
