The In-FUN-ity™ Cut-out Climbing Wall is designed for the child who is not fully comfortable using the standard rock on most climbing walls and has (21) cutouts where your clients can insert hands and feet. The hook-shaped top attaches easily to the In-FUN-ity Wall Ladder (items 152000, 152001, 152002) or the Expansion Kit Ladder (item 152013). Since it can attach to any rung, you can adjust it to fit the abilities of your least adventurous clients.
