Roll up doors are commonly used in commercial and industrial settings due to their durability and space-saving design. However, over time, the cables that support the door’s movement may wear out or break, requiring replacement. In this guide, we will discuss the process of roll up door cable replacement in detail, providing you with valuable tips to ensure a smooth and hassle-free experience.

Understanding Roll Up Door Cables

Roll up door cables play a crucial role in the proper functioning of the door. They are responsible for lifting and lowering the door, allowing for easy access and enhanced security. These cables are typically made of high-strength steel, ensuring they can withstand the heavy load and frequent use.

Signs of Cable Wear or Damage

Before proceeding with the replacement, it’s important to identify signs of cable wear or damage. These may include fraying, rusting, or visible breaks in the cables. Additionally, if you notice the door becoming increasingly difficult to open or close, it could be a sign of cable issues.

Steps for Roll Up Door Cable Replacement

1. Safety First: Before starting any repair or replacement procedure, ensure that the power to the door opener is switched off, and all safety precautions are taken. This includes wearing protective gear such as gloves and safety glasses.

2. Gather the Necessary Tools: To replace the roll up door cables, you will need a few essential tools, including a ladder, wrenches, pliers, and a cable cutter. Make sure you have everything on hand before starting the replacement process.

3. Release the Tension: To remove the old cables, you need to relieve the tension in the springs. This can be done by disconnecting the door from the opener and manually lifting it until the tension is released. Be cautious during this step, as the door may suddenly drop if not properly supported.

4. Remove the Old Cables: Once the tension is released, carefully disconnect the cables from the drum and bottom bracket. Use the appropriate tools to loosen any fasteners and remove the old cables from the door assembly.

5. Install the New Cables: Take the new cables and feed them through the appropriate channels, ensuring they are properly aligned with the drum and bottom bracket. Use the cable cutter to trim any excess length, leaving enough to securely attach them to the drum and bracket.

6. Reattach the Door: Once the new cables are securely in place, it’s time to reattach the door to the opener. Carefully lift the door and reconnect it to the opener, ensuring it is properly aligned and balanced.

7. Test the Door: After completing the replacement, test the door’s functionality by opening and closing it several times. Pay attention to any abnormal noises, jerky movements, or signs of cable slippage. If any issues are detected, revisit the installation steps and make necessary adjustments.


Roll up door cable replacement is a crucial maintenance task to ensure the smooth operation and longevity of your commercial or industrial doors. By following the steps outlined in this guide, you can confidently replace the cables and restore your roll up door’s functionality. However, if you are unsure or uncomfortable with the process, it is always recommended to seek professional assistance to avoid any further damage or accidents.
