BUILD YOUR OWN CLIMBING WALL: The DIY Panel makes it easy to create a professional-grade climbing surface at home, in your garage, or anywhere you want to train with the 4' X 2' Easy to Handle Sized Panels which fit on 16' and 24" Spaced Wall Studs (NOTE: exact size of panel is 48"x23.75") PRE-DRILLED & READY TO SET: Each panel comes pre-drilled with standard 3/8-16 T-nuts installed on a 8" grid pattern allowing you to quickly install holds and start climbing without extra prep work. DURABLE CLIMBING SURFACE: Constructed from high-quality Baltic birch, these panels are built to handle years of abuse from dynamic moves, repeated falls, and heavy setting. CUSTOMIZABLE CONFIGURATION: Mix and match panels to design walls that fit your space, whether you’re building a vertical trainer, overhang, or full home gym. PERFECT FOR ALL CLIMBERS: Whether you’re building a climbing wall in your childrens bedroom, or you're an experienced setter building a custom project, the DIY Panel is the ideal foundation for your climbing goals. NOTICE: These panels include USA standard 3/8-16 size t-nuts, Amazon often recommends a non compatible hold package with metric M10 bolts which is the standard size in Europe/Asia. The DIY panels are designed and engineered to make building your climbing wall as easy and painless as possible. Just unbox and start installing onto your 16" or 24" on center studs. The panels are textured, drilled, and t-nutted saving you hours of work. Our goal is to provide a commercial gym caliber panel to the DIY market. This is why we use 13 ply baltic birch, our self-guided industrial t-nut, and our industrial long lasting texture. Walls are designed for indoor use or covered outdoor structures. The 2'x4' size makes it easy to install with one person and weighs in at 21lbs. This size also makes it easier to add different wall angels and transitions. The 8" square t-nut grid is designed never to hit studs (16" or 24" standard stud spacing) and to flow seamlessly from one panel to the next. With 18 t-nuts (threading 3/8-16) per panel you will have plenty of modularity and options for routesetting.
