Space-saving system now offers a clear climbing surface so adults can easily see multiple students climbing on both sides. Clear panels are made of UV-resistant polycarbonate that resists dirt and smudging. Gray panels are made of a closed-cell, high-grade polymer. All systems are weatherproof and anchored to powder-coated steel posts that mount in ground for stable climbing almost anywhere; install only over fall surfacing rated for a 6' or 8' fall height. Includes 120 holds and mounting hardware. Truck delivery.
