Polanik Hammer Insert Conversion Circle The Polanik Fiberglass Hammer Ring is designed to fit inside a standard discus circle, instantly converting it into the smaller diameter required for hammer throw. It's a practical, space-saving solution for facilities that host multiple throwing events in the same area. The ring breaks down into four sections for easy transport and storage, then quickly reassembles for competition. 🏅 Coach Cappos Recommends "For facilities that don't have a dedicated hammer circle, this insert is the most practical solution I've seen. It drops right into your existing discus ring, holds up to real competition use, and breaks down fast when you need the space back for discus. I recommend this for any program running both events on a single ring."
