thule square bar hook mount

Hook mount for the Thule square bar roofrack For me its meant to hook a small triangle style garden sail into it when i am parked at campsite or after i am done riding my mountain bike and i want a place to relax in the shade. The hooks gives the 2 points of the sail to hook into and the last one can be hooked into a tree or other. You can also use it the hang what ever else you want from it. Used a set of 40mm long M3 screws and wingnuts to assemble it all on the car roof rack There are two different bottom plates with the design, one allows for more clearance on the square bar and the other have an extra "ridge" that will slot into the top part of the holder should you square bar be slimmer / worn down. Warning. I dont thing this item is strong enough to hold anything on the roof rack while driving
