Set of boxes indicating the distance thrown in discus, hammer, and javelin events. It includes an adhesive vinyl on each of the three vertical faces with the distance from the centre of the throwing area, indicated in metres, for the perfect view from any location in the stadium.
The box has a triangular base and is made of polyester reinforced with fiberglass. Its own particular design allows them to be stacked for optimal storage and transport.
The set consists of 28 marker boxes with two units per each number. The boxes are numbered every five meters, from 30 to 95, inclusive.
