moving parts allow it to be packed flat and compact, the two straps are how you keep the top and bottom sections togethers and make it rock solid when you get up the tree. Those same two straps allow you to tighten the two sections together for quiet packing through the woods.

Oh BTW, you dont exactly have to guess when attaching to the tree, once you use it enough you'll find a quick and safe way to adjust it

Don't worry, after a few uses you'll find your groove with this stand.
