One、What is a sliding door track system?
Sliding doors with rolling rails are doors that slide open and closed using rolling rails. These sliding doors do not have a lower rail, resulting in quiet operation and no thresholds, making them aesthetically pleasing and practical. They are suitable for balconies, dining rooms, kitchens, and bathrooms, and are a popular choice for many families.
Two. Installation instructions for sliding doors with rails.
Installing sliding doors at home is a great option, as they don't have a bottom rail, making them safe to use, especially for families with elderly or young children. Installing sliding doors is also relatively easy. Here's an introduction to the installation method:

1. Open the packaging and carefully inspect the sliding door products and accessories for any damage.
2. Remove from the frame and place with the material facing upwards to prevent scratching.
3. Install sliding rollers, placing them in the upper slide channel in the correct order. Assemble the frame and crossbeam correctly, and tighten with half-length self-tapping screws.
4. Place the installed door frame inside the door opening. First, ensure that the left and right door frame edges are level and plumb, mark the positions for drilling, and fix them with expansion screws. Note that the screws should not be tightened excessively, as this will allow for minor adjustments when installing the door leaf. If the gap is too large, fill it with thin boards or other objects.
5. For doors with no air vents, directly drill holes at the appropriate position in the sliding groove using a drill bit, and secure with a pin. For doors with air vents, ensure they are level and vertical, insert them into the upper guide rail, and then drill holes and secure them with expansion screws after installing the air vent.
6. Re-adjust the entire door frame horizontally and vertically to ensure it is level and plumb, then tighten all screws.
7. Ensure that the rollers are at the same height and consistent with the site height. If not, adjust them to the appropriate position. If they are equal, install the pull-up door directly on the track.
8. After installing the sliding door, re-adjust the horizontal position of the sliding wheel, ensure smooth operation and accurate locking, and then prepare to install the positioning wheel.
9. Ensure the door is in a natural vertical position and mark the correct location for the sliding door positioning wheel. Remove the door leaf and fix the positioning wheel using the appropriate screws.
10、 Install the door hinges, check if the gap between the sliding door and the frame is even. If not, adjust it slightly to the correct position and test the door's level, smooth sliding, and the smooth, safe operation of the lock. once the desired result is achieved, remove the sliding door track, tighten the positioning wheel screws, reinstall the sliding door track, and adjust the sliding wheel positioning screws.
Three, what are the installation precautions for sliding doors?
1、When installing sliding doors with guide rails, it is essential to ensure that there is sufficient space. It is not recommended to install sliding doors with guide rails in spaces with limited front and rear clearances.
2. Before installing sliding doors with guide rails, it is essential to ensure that the door opening is wide enough for two doors to pass through.
3. If installing two sliding doors, it is necessary to measure the width of both doors beforehand to ensure they are the same, which will prevent aesthetic issues. During installation, it is also important to ensure that the gaps between the two doors are aligned, otherwise, installation may result in an uneven appearance.
4. After installation, check to ensure that the sliding doors open and close smoothly. Then, secure the door leaf using screws and bolts to avoid the need for rework.
