These mini features add depth and variety to any wooden climbing wall. They are cool because they are just big enough to match hands or cross on, but not so big as to make it too easy on you! And all of the micro-featuring can be used as mini hand or footholds to increase Training difficulty. They're featured, fun AND they can go ANYWHERE on your wall and are not reliant upon a t-nut to locate them. (All holds come with our heavy-duty, self-driving decking screws for easy application.) Add variety to your Training and keep things diverse, fun and interesting! Please let us know in the customer comments section which style you would like.
