Set of prisms indicating the distance thrown in the shot put competition. The set includes six prisms, to place three on each side of the launch sector, and a set of 28 numbering plates (from 10 to 22, every 2 meters).
Each indicator is made up of a triangular prism-shaped casing made of polyethylene (PE), and two numbering plates fixed to the casing by means of four magnets each.
The casing is made by rotational molding in polyethylene, with a textured exterior finishing. This material has protection against ultraviolet UV rays and is unalterable to atmospheric agents.
The sheets are made of steel, and are subjected to a powder painting treatment
