Installation tips for best results
- Verify your track and roller configuration are compatible with a 5/8 in. diameter, 3-1/8 in. length adapter before starting.
- Align the adapter with the mounting points on the door or track bracket, then secure using the included hardware. Ensure hardware is tightened firmly but not overtightened to avoid stripping.
