Maintenance Tips for Extended Garage Doors

- Check Fasteners: Ensure extension brackets are secure to prevent sagging.
- Inspect Springs and Cables: Taller doors exert more tension—inspect quarterly.
- Test Door Balance: Disconnect the opener and manually lift the door; it should remain open halfway if balanced.

| Door doesn’t open fully | Extension too short or misaligned | Recheck rail alignment and connections |
