Plug for approx 40 mm hole

These plugs are meant to be inserted into a hole of approx. 40 mm diameter (ideally in flexible material, e.g. the lid of a plastic box, with a thickness of around 1 mm).


Plug_recessed: At the base, the diameter is strongly reduced in order to hold on strongly.

Plug_not_recessed: At the base, the diameter is very faintly reduced in order to hold on loosely.
