How to replace the door & window roller?

1. First of all, set up the upper pulley part of the sliding door when in the replacement, which will facilitate the subsequent steps.

2. Also remember to pull out the wool top, you can insert a 6mm hexagonal wrench from the hole, that it is the most suitable.

3. If you feel that you are struggling, you can use the short end of the wrench to insert the inner six holes of the screw, and then rotate it.

4. After loosening the screw, the upper pulley can be pulled out in parallel at this time.

5. Then install it with new screws.

6. Push the upper pulley flat into the gap between the screw cap and the inner wall of the door frame. To keep the upper pulley at a certain distance and remember to leave a cardboard between the upper edge of the door frame and the plane of the upper pulley.

7. Then tighten the screws.

8. The upper pulley is installed. At this time you can remove the cardboard

9. Turn the sliding door over and tree it up. At this time, you can insert the screw through the round hole at the bottom and hold the lower pulley down by hand. By doing this, you can adjust the square screw hole to be perpendicular to the screw, and screw it easily. Use a 5mm hexagon wrench to tighten the screw.

10. After the screw is screwed into the adjustment block, five more rotation is enough. So far, one side of the upper and down pulley of the sliding door have been installed. The installing methods of the other upper and lower pulleys are the same.

11. If the sliding door is not flat after it is installed on the rails, you can continue to adjust it with a 6mm hexagon wrench. Clockwise rotation is up, counterclockwise rotation is down.
