Portable structure for shot put, especially suitable for indoor tracks. Measuring 3 x 3 meters, it can be disassembled into two 1.5 x 3 meter parts to facilitate transport and storage.
Each of the two halves consists of a tubular steel frame plus two wooden boards. The top board includes a semi-circular cut-out to house the 2,135 mm inner diameter metal circle (AL050).
The wooden shot put toe board (AL060) is also mounted on one of the structures. In addition, white lines are painted on the upper boards, which are used to declare a shot put null or not, in accordance with World Athletics Regulations.
To facilitate correct assembly, one of the two frames has three rods that fit into the respective holes in the other frame. Once in position, the frames are linked by two pull fasteners.
