EX-502A 6mm glass metal wheels sliding plus shower door

How do I adjust a metal wheels sliding shower door if it's out of alignment?
The method of adjusting a metal wheels sliding shower door may vary depending on the manufacturer and model, but generally follow these steps:
Check the tracks and pulleys: First, check the shower door's tracks and pulleys to make sure they are not damaged or clogged. Remove any debris or dirt that may interfere with sliding.
Loosen the set screws: There may be set screws at the top or bottom of the door that adjust the door to be horizontal or vertical. Use an appropriate tool, such as a screwdriver, to loosen these screws.
Adjust Leveling: If the door is not level, you can fix it by adjusting the top or bottom pulleys. There are usually some screws or nuts that can be used to adjust the height of the pulley so that the door remains level.
Adjust the verticality: If the door is not vertical, it can be solved by adjusting the pulleys on the sides. Similarly, find the corresponding screw or nut and gradually adjust the position of the pulley until the door is vertical.
Set Screws: Once adjustments are complete, be sure to retighten all set screws to ensure the door remains in the correct position.
Test the slide: After adjustments are made, test the door's slide to make sure it opens and closes smoothly and remains level and vertical.
If the above steps do not resolve the issue, you may need to refer to the manufacturer's specific adjustment guide or contact a professional for adjustment.
