Fix window sashes 2 (aluminum or plastic)
Do you have window frames and sashes made of plastic or aluminum? In order to fix partially opened casements, you do not necessarily have to drill on the construction parts.
A holding plank made of wood or metal, placed between the frame and the wing, prevents closure in wind or draft. So that the plank itself does not slip, it has a retaining groove at the outer end. Other solution variants of the holding plank are possible.
An undesirable further opening of the window sash is braked by an eccentric; rotatably mounted on the holding plank. Moving the plank along the windowsill gives you the option of opening the window a little or very far without the window sash moving.
