Pin for coil holder

The pin must be placed inside the central hole of the coil holder. Its cylindrical smooth part allows the rotation in neutral; two little wings, diametrically opposite, impede to the bowl to lift up and go out from the support.

The square-shaped part is necessary for mounting the cover: 2 plastic ribs impede to the cover to go out from its place when recovering the surplus of the cable. So, the skein is safe and protected. To remove the cover from the pin, leverage with the plastic ribs on the higher part and pull it out.

The central square-shaped part is realized for stopping the coil holder on the central mast of the frame.
