Set of boxes indicating the shot put distance in shot-putting events. It includes on each of the three vertical faces an adhesive vinyl with the distance from the centre of the throwing sector, indicated in meters.
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 14 boxes with two units per each number. The boxes are numbered every meter, from 14 to 20, inclusive.
