Gill Hammer Conversion Circle; 7 Piece

The Gill Hammer Conversion Circle lets a facility turn an existing discus ring into a legal hammer ring in seconds — no permanent construction required. Its seven interlocking PVC sections drop into place to adapt a standard circle to exact hammer specifications, making it the practical solution for schools that share a single throwing area across multiple events.

Key features & specs:

• Design: Seven interlocking sections of durable white PVC plastic
• Function: Converts a discus ring into a regulation hammer ring
• Setup: Portable; installs in seconds with no permanent fixtures
• Compliance: Meets NFHS, NCAA, and World Athletics specifications; IAAF certified
• Model: GP-3622

Coach's tip: Seat all seven sections fully so the ring sits flush and continuous before any throw, and pair it with a single-circle hammer cage for safe practice. Store the sections stacked and out of prolonged sun, and count them back in after each session so the set stays complete.
