Bathroom door handles are both indoor and outdoor handles. If the door handle is off, most of the screws are loose, so check if the screws are still in the holes on the handles. If they are, use screws to tighten them. On the contrary, if it is not there, it is recommended that you ask for a screw where you sell glass accessories! I will answer you sincerely! Look at the picture. In this case, the screw is still on the handle, and you are on the side where the handle is dropped. When you see a screw, you use a cross screw to twist it down, and then there is a section. You can connect another screw to the hole on the glass door with the handle that is not dropped, and then tighten the screw that was previously twisted. Solve the problem!
