This is my roof rack for carrying my 17' 47 lb. kevlar canoe.
There is a pair of these, the second is in the back ground. The risers are wood from 2x4's cut out using a 3-1/2" hole saw, they are 2 tall. I've inserted stainless 1/4" carriage bolts. The 2 pieces are epoxied together and to the fiber glass roof.
The metal pieces are scrap aluminum awing arms. I used 4 risers on each for 2 reasons, 1 it gives me some adjustment between the 2 carriers, 2 it eliminates side twisting.
Also I use a piece of Unistrut temporarily fastened to the top of the ladder, with pipe clamps, when I drag my canoe up and down.
Clear as mud?
Have a question? just ask.
