Throw & Conversion Rings

Track and field facilities often need to support multiple throwing events within a limited footprint. Throw and conversion rings by Sportsfield Specialties provide a flexible solution by allowing a single throwing circle to be adapted for shot put, discus, or hammer events. By adjusting the usable diameter of the circle, these systems help facilities meet event-specific requirements without the need for additional construction.

Designed for secure installation, conversion rings fit within an existing throwing circle and create a consistent, regulation-compliant surface for each event. Available in aluminum angle and web-reinforced styles, these rings are built for durability and long-term performance in high-use environments. Integrated features like recessed screed lines support clean concrete finishing and help ensure proper alignment during installation.

Conversion rings are commonly used at high schools, colleges, and multi-use athletic complexes where space efficiency is critical. By allowing one throwing area to serve multiple disciplines, they help maximize facility usage while maintaining compliance with World Athletics, NCAA, and NFHS standards.

For a complete throwing area installation, conversion rings can be used alongside ThrowForm® throwing pad forming systems to ensure the surrounding concrete pad is built to exact specifications. While conversion rings provide flexibility within the circle, forming systems help establish proper dimensions, edge definition, and drainage during construction, resulting in a more consistent and long-lasting throwing surface.

By combining adaptable ring systems with precision construction tools, facilities can reduce build costs, improve versatility, and deliver a high-quality throwing environment for both training and competition.
