3. Installation Instructions
Follow these steps for proper installation of the sliding closet door roller kit:
- Remove Existing Hardware: Begin by removing the center guide from your closet door system. Lift the door upwards and tilt it out of the track to remove it.
- Install New Brackets: Remove any old brackets from the door panels. Install the new roller assemblies (brackets) onto the door panels using the provided fasteners. Ensure the correct roller assembly (1/8 inch offset for front panel, 3/8 inch offset for rear panel) is used for each door.
- Level Doors: Once the new brackets are installed, re-hang the doors. Level the doors as needed before tightening all screws securely.
- Check Adjustment: Before finalizing the installation of the guide, check for proper adjustment of the rollers to ensure smooth operation.
A soft mallet may be required for certain installation steps.

4. Adjustment
Each roller assembly features a height-adjustment dial. This allows for fine-tuning the door's height to achieve a perfect fit and smooth gliding action within the track. Adjust the dial as necessary to ensure the door is level and moves freely without binding.
