Sliding Shower Door Will Not Stay Closed

Lower the door down from the overhead track.
Sliding shower door will not stay closed. Remember each side frame has a bumper preventing the doors from closing completely. I have a standard sliding door on the shower tub. You re most likely facing one of the following. It may take a little hit and miss until you get the door to sit level and properly seated in the track.
The shower doors rollers can be adjusted accordingly. The shower door doesn t stay closed. Most sliding doors have a mechanism called an adjusting screw located at the bottom of the door ends. I just installed sliding doors in the master bath.
Turning this screw raises or lowers the roller. Close the bifold doors and see if they pop open. Shower door keeps popping open and won t stay closed shower door scrapes the bottom of the shower pan edge when opening and closing shower door is loose and needs tightening. It slides along the top of the tub.
If they do lift up on the bifold door and slide the bottom of the panel that is nearest the door casing to the side so that the bottom pin slips out of the bottom bracket. It won t stay shut. This is a simple repair to a common problem. Your sliding door might be able to latch if you hold it and lock.
Easy peasy with the directions. If the door becomes even harder to open turn the screw in the opposite direction. Give the screw a clockwise turn and test to see whether the door slides easier. In your case because the door slides open you ll need to either raise the back of the door or lower the front of the door that should be hitting the rubber stop in the closed position by changing the position of the roller.
My super recalibrated it there are four screw holes for the top runner and he put it on the last one but it still slides back.
