First slide open the door completely and remove the head stop.
Sliding door moves hard.
Tinker around with the roller screws to see if the door glides better when it s at a lower or higher height.
Never leave the glass door unattended.
Slide the door open and shut to move the lubricant around the track making sliding easier.
If the sliding door is still sticky after the tracks have been cleaned use powdered graphite or silicone lubricant to ease things along.
Because sliding doors don t fold out the way bifold doors do they allow access to only half the width of the opening at a time.
Then lift the door up and out of the track laying it down carefully across two sawhorses.
When there s dirt in the door track it not only makes it hard to open and close the door it may cause serious damage if the door jumps the track when it hits an obstruction.
Sliding doors are very heavy very breakable and very expensive this is a two person job.
Rub a thin layer of dry lubricant to the track.
Do not use oily lubricants on the track as this can.
