Add a Rock Climbing Wall to Your Walnut Modular This add-on rock wall panel turns one section of your 95 inch Avenlur Walnut Modular into an indoor climbing wall. Colorful climbing holds give kids a new challenge on the same wall gym, so the play space grows as your child does. It's made from smooth New Zealand pine and installs with the included hardware. Why Add the Rock Wall Panel A new climbing challenge: Rock holds work grip strength, balance and problem solving in a different way than ladder rungs.

Tested to ASTM and CPSIA standards: Smooth New Zealand pine built for everyday indoor climbing. Build Your Wall Gym Your Way The Walnut Modular is designed to change with your family. Pair the rock wall with our ring wall panel, rope wall and ladder panels, or add monkey bars for even more ways to climb. Walnut Modular sold separately.
