Gill Shot/Hammer Circle; Aluminum W/2in Angle

Install a heavier-duty permanent throwing circle with the Gill Shot/Hammer Circle built from 2" x 2" extruded aluminum angle. The deeper angle profile gives this cast-in-concrete ring extra structural mass and edge definition, standing up to years of shot put and hammer competition while holding the precise regulation dimensions throwers depend on for legal, consistent footing.

Key features & specs

• Two sections of 2" x 2" extruded aluminum angle for a robust, deeper-profile permanent circle
• Designed to be cast into concrete for a durable, flush in-ground installation
• Heavier angle stock provides added structural mass and a well-defined circle edge
• 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 meet after meet

Coach's tip: level and align the circle precisely before pouring, as the installation is permanent once the concrete cures — a flush, true edge is critical for both safety and legal throws. Match it with the correct compatible toeboard for your event, and keep the aluminum rim clear of dirt and debris so throwers get clean, reliable traction.
