I'm not home so I cannot give an exact answer; but I believe they are about 18"
These blocks are cut on the top. The angle is in the top as well, which doesn't really allow for them to fit bars correctly. I tried turning them over to fit my bars and they would not work.
I run the strap over the kayak and through the car door and then shut the door on the strap. No problems so far
I do not leave them out in the elements on my vehicle for the weather to damage them.
