Gill Shot/Hammer Circle; Aluminum

Set a permanent, certified throwing circle into your throws area with the Gill Shot/Hammer Circle in extruded aluminum.

Key features & specs

• Four sections of 1" x 3/4" extruded aluminum angle for a lightweight, corrosion-resistant permanent circle
• Designed to be cast into concrete for a durable, flush, in-ground installation
• Discus-circle capable: the circle can also be surface-mounted for discus applications
• Compatible with toeboards 358 and 363 to complete a shot put or hammer setup
• Meets NFHS, NCAA, and World Athletics specifications for competition-legal throwing
• Regulation dimensions for consistent, certified footing

Coach's tip: position and level the circle carefully before the pour, since it becomes permanent once the concrete sets — a flush, true ring is essential for safe footing and legal throws. Pair it with the correct compatible toeboard for your event, and keep the aluminum rim clean and clear of grit so athletes get consistent traction at the front of the circle.
