Gill Throwing Surface For Indoor Circle

The Gill Indoor Circle Throwing Surface addresses the most overlooked variable in indoor throwing events — what's underfoot. A proper hard throwing surface inside the ring is the difference between confident, technically sound throws and slipping, inconsistent footwork that undermines an athlete's mechanics. This three-piece birch plywood insert installs directly onto the circle and meets full competition standards.

• • Premium 3/4" 7-Ply Birch Plywood — Dense, high-grade birch plywood construction provides a rigid, non-compressible throwing platform that resists the repeated lateral and downward forces of shot put and weight throw footwork — maintaining a flat, stable surface through an entire indoor season of practice sessions and competition use without warping or developing soft spots
  • Three-Piece Modular Construction — Surface is divided into three separate sections that fasten to the underside of Gill's Indoor Shot/Weight Throw Circle, covering the full interior of the ring with a seamless, flush throwing platform that installs and removes cleanly without permanent attachment to the gymnasium floor
  • Designed Specifically for Gill Indoor Circle — Engineered to attach directly to the underside frame of Gill's Indoor Shot/Weight Throw Circle as a factory-compatible accessory, ensuring a precise fit with no gaps between the plywood surface and the aluminum ring band that could catch an athlete's foot during rotational movement
  • Consistent Footing Across All Throw Phases — Hard birch surface delivers uniform traction and grip characteristics from the back of the ring through the power position and release, giving throwers the predictable underfoot feel needed to execute technically demanding rotational shot put and weight throw technique with full confidence
  • Eliminates the Problem of Bare Gymnasium Floors — Indoor gymnasium surfaces — whether hardwood, rubber, or synthetic — vary in grip, texture, and hardness in ways that directly affect throw consistency and athlete safety; the birch plywood insert standardizes the throwing surface regardless of what the underlying gym floor is made of
  • NFHS, NCAA, and IAAF Compliant — Meets all governing body specifications for indoor shot put and weight throw competition at the high school, collegiate, and international level, making it a competition-legal surface for sanctioned indoor meets without requiring permanent facility construction or modification
