Here are a couple pics i took before i went into the office at work.
The main length i do no know with out measuring...but the little tabs on the sides are 2" x 3", and the square tubing is 2" x 1"
I made that instead of using the rack parts going across for 3 reason:
- Can Be removed Quickly...ex i like to go canoeing
- brings it up closer to the front.
- I am already using the rack to help keep the tire on the roof from sliding around...eve though it is strapped down.
