Innovative Throwing Technologies Discus To Shot Put Hammer Weight Throw Throwing Circle Conversion Inserts

This is a lightweight modular conversion ring for a Discus circle to Shot Put, Hammer, Weight Throw Circle.   NOT INTENDED AS A STANDALONE CIRCLE Using keyed foam mats we cut out the proper size insert to take the 2.5-meter circle to a 2.135-meter throwing circle. We use a large laser router to cut a smooth accurate insert to the proper size. The pads lock together to form the insert.  The insert fits snugly in the discus circle.  The mats are heavy-duty 3/4  inch thick. The circle is accurate to within .5 diameter due to the expansion and contraction of foam.  We get material in 3 different colors and depending on availability the one shipped maybe sky blue, silver/grey or black.
