AAE's throwing form system is designed for both discus and shot/hammer events, providing a durable and precise foundation for concrete throwing pads. The system features a welded aluminum concrete form with nominal dimensions of 10' x 10' x 6" and includes 2" x 2" x 1/4" thick aluminum angle circles, with diameters of 8'-2½" for discus and 7'-0" for shot/hammer. Assembling in two halves, the form incorporates the Concrete-Flo™ design system grid pattern for accurate installation. A 3/4" offset concrete screed line is included for discus events, and integrated drain tubes ensure proper water displacement into a crushed stone sub-base.
