Oh and you can make the XL belts (or the regular ones for that matter) go down to fit even the smallest diameter tree with a slight modification to the factory build.
GReg figured it out this season because he wanted to climb a tree in a fencerow about the diameter of a Lollipop stick and couldn't. LOL

He got to looking at what was keeping the platform belt from going all the way down and through like the climber section (hand climber) and figured out if you reversed the nut/bolt set up they use to clean up the lines of the stand it opens the channel to allow the belt to travel all the way through rather than stop when the ends hit the bolt.

I haven't gotten around to doing that to mine as I don't have much desire to climb teeny tiny trees, but Greg got a kick out of solving the problem and there isn't a small tree he can't climb now.........I know I'm gonna find him sideways bent over in a sapling one day.
