My climber didn't come with straps. I bought some, similar to yakuza's, from Basspro. The top portion of my stand kinda slips over the bottom portion and I tie them together tightly with my gear rope (rope I use to pull my gun/junk up once I'm in the tree). Just tie one end to the top part, set them together tightly, and loop it around. Tie the rope to itself and you're golden. Good luck.
