This rack will NOT hold up to the wind from normal driving conditions.
This rack broke on me during normal use conditions, on the first trip out.  The crosswind (20mp) bent the rack with kayak still strapped to it.  The hollow tubing did not hold up to a standard 9ft kayak in normal driving conditions. I tore my bicep trying to unleash the thing from the bent rack on the side of the highway.  I don't suggest this AT ALL if you want to go more than 3 blocks with it.  I attached photos of the broken j-rack, after I bent it back far enough to get the kayak off the roof.  It was a nightmare situation.
