    Frequently Asked Questions

    What if the garage door doesn’t balance after adjusting the cables?

    It might be due to uneven tension in the cables. Re-adjust the cables to ensure equal tension on both sides and recheck the balance. If the issue persists, contact us for professional assistance.

    Can I use lubrication on the cables?

    Yes, lubricating cables can reduce friction and prolong their life. Use a silicone-based lubricant and avoid grease, as it can attract dirt and debris.
