Throwing Circles & Toeboards

The Gill Shot/Hammer Circle Form in aluminum gives throws programs a permanent, competition-legal foundation for shot put and hammer events. Designed for in-ground installation, the four-section form bolts together into a perfectly true circle and serves as the mold for a smooth, crack-resistant concrete pour — delivering the consistent, level throwing surface athletes and officials expect at sanctioned meets. Once set, it becomes a fixed part of your facility that will handle years of daily practice and competition without shifting or degrading.

Key features & specs

• Four sections of 2" x 3" aluminum angle that bolt together to form the circle
• Built for permanent in-ground installation
• Aluminum exterior bracing creates a strong, rigid frame that holds shape during the pour
• Open center allows a smooth concrete pour and a crack-resistant finished surface
• Inner circle constructed of 1/4" x 3" flat aluminum bar
• Compatible with Gill toeboards 358 and 363
• Meets NFHS, NCAA, and World Athletics specifications

Coach's tip: Pair the form with a matching Gill toeboard (358 or 363) so your circle is meet-ready from day one. Care: Aluminum construction is corrosion-resistant; keep the circle surface swept clear of debris and standing water to preserve traction and extend service life.

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.

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

• 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.

Build a competition-legal throwing circle that holds its shape for the life of your facility with the Gill Shot/Hammer Circle with cross bracing. Its two-section extruded-aluminum design with welded bracing bolts together into a rigid, true ring that resists the distortion cheaper circles suffer during in-ground installation — giving throwers a consistent, certified footing meet after meet.

Key features & specs

• Two sections of 1/4" x 3" extruded aluminum with welded bracing for maximum rigidity
• Bolts together to maintain true circular form during in-ground concrete installation
• Mounting hardware included for a complete, ready-to-set installation
• Compatible with toeboards 368 and 363 to complete a shot put or hammer setup
• Meets NFHS, NCAA, and World Athletics specifications

Coach's tip: assemble and bolt the circle fully before the concrete pour so it locks in a perfectly round shape, and set it flush and level with the surrounding surface for safe footing. Pair it with the correct compatible toeboard for your event, and keep the aluminum clear of debris so throwers have clean, consistent traction.

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

The Gill Indoor Shot/Weight Throw Circle gives programs a portable, competition-legal throwing ring for indoor shot put and weight throw.

• Compatibility: Works with 366, 369, and 374 shot circles and the 3741 form
• Compliance: Meets NFHS, NCAA, and World Athletics specifications; IAAF certified
• Model: GP-363

Coach's tip: Confirm your circle uses a depressed (3/4") pad before ordering so the aluminum board seats flush and legal. Check the anchoring before each session, and wipe the board down after wet meets — aluminum won't rot, but keeping it clean protects the painted contact surface throwers rely on.

The Gill Shot Toeboard (Synthetic, Level Pad) is the surface-mount version of Gill's durable polyethylene stop board, built for shot put circles installed flush with the surrounding pad. Molded from low-density polyethylene, it delivers the reliable, regulation-legal contact edge throwers need while standing up to season after season of hard use.

• Material: Molded low-density polyethylene
• Fit: Designed for surface-mount (level pad) shot circles
• Compatibility: Works with the 372 aluminum and 373 steel shot circles
• Compliance: Meets NFHS specifications
• Model: GP-359

Coach's tip: Match the toeboard to your circle type — this level-pad version pairs with surface-mount 372 and 373 circles, not depressed installs. Confirm it's anchored flush and secure before every session so throws stay legal and safe, and store it out of prolonged sun to protect the synthetic material.

The Gill Shot Toeboard (Synthetic, Depressed Pad) gives shot put circles a durable, competition-legal stop board that holds up to repeated contact from the shot and the thrower's foot. Molded from low-density polyethylene for a 3/4" depressed surface, it's built to meet the specifications officials require while resisting the cracking and chipping that shortens the life of lesser toeboards.

Key features & specs:

• Material: Molded low-density polyethylene with a 1/4" wall thickness
• Fit: Designed for a 3/4" depressed pad surface
• Compatibility: Works with 366, 369, and 374 shot circles and the 3741 form
• Compliance: Meets NFHS, NCAA, and World Athletics specifications
• Model: GP-358

Coach's tip: Confirm your circle type and pad depth (depressed vs. level) before ordering so the toeboard seats flush and legal. Check that it's securely anchored before each session — a loose toeboard is both a foul-line and a safety issue — and store synthetic boards out of prolonged sun to keep the material from getting brittle.

The Gill Portable Discus Platform gives throws programs a regulation practice and competition surface that can be set up, moved, and stored without a permanent concrete installation. Its portable, interlocking design is ideal for schools that share facilities or need to clear the throwing area for other events — roll it into place for practice, then break it down and store it out of the weather when you're done.

Key features & specs:

• Overall dimensions: 10' x 10' x 2"
• Construction: Two layers of ¾" plywood topped with a ½" track-surface layer
• Sections: Two 5' x 10' interlocking halves with spring-loaded handles for easy handling and storage
