Allen Briggswrote a review of Thule Load Strap - 2 Pack on October 2, 2008
I use this with my hull-a-port kayak rack and it works well. I never have any problems with the boat slipping. It is easy to tighten these down, and easy to loosen them as well. I have full confidence in the durability of these. They are very well made. You can trust in Thule products!
