/> Hollowback technology, used in climbing holds, is a design method where the back of a large hold is hollowed out.
Instead of a heavy and rigid polyurethane or resin block, this holds has a thin outer shell reinforced with internal structural ribs or lateral supports.
How it Works;
• Shell Design: The front of the shell looks normal, but the back is completely open or hollowed out.
• Internal Supports: Thin material protrusions inside the hollow prevent the hole from bending or cracking under pressure. We create a specially developed spiderweb structure here.
• Material Savings: Less raw plastic or resin is used per piece during casting.
Key Benefits;
• Lighter Weight: Large angled holds and arms become much easier for route setters to transport, lift, and wall-mount.
• Cost Efficiency: Reduced material usage and lower shipping weights save money for manufacturers and gyms.
• Improved Scalability: Manufacturers can create massive and ergonomic shapes without making the handles so heavy that they can't be securely bolted on.
