Roll Up Door Cable Replacement

If you are thinking about your roll up door cable replacement, then we can help you. The single most important point to remember in working with a two spring operated roll up door, is that most of the procedures are administered while keeping the door open. The procedure to replace the cable in a roll up door is as follows:

Opening the door and pushing it back into the horizontal track. It should be done in such a way, that the bottom panel of the door is more or less 16 inches from the header. This generally requires at least two men.

  • Placing a clamp in each track securely and tightly, immediately below the roller at the bottom.
  • Determining the type of installation, which would either be a shallow or a standard header. The balancer in a shallow header is concealed and the header itself measures approximately 5 inches. On the other hand, the balancer in a standard header is openly visible, while the header itself measures approximately 6 inches.
  • Loosening the set screws located in the winding cone, preferably with a 7/16” box-wrench.
  • Ensuring the freeing of the spring assembly, making it easy to spin on the shaft.
  • Winding the new cable on to the cable drum, while following the grooves. In case of a shallow header, the cable would come off the top of the drum, while in regular headers, the cable would come off the bottom.
  • Winding the balancer by insertion of bar into the winding cone.
  • Counting turns immediately after the cone rotates. 3.5 to 4 turns are ideal..
  • Tightening the set screws in a secure manner.
  • Removing the clamps in the tracks with extreme care.

Working on roll up doors and some of its related parts entail a significant amount of physical danger. If you don’t possess the relevant training and experience in roll up doors installation and/or repairs, you should seriously consider leaving the job up to the professionals to avoid serious injuries to yourself.
