Decoding Garage Door Cables: Selection, Assembly, and Upkeep

Choosing the right garage door cable is crucial for ensuring the proper functioning and balance of your garage door assembly. This blog post will cover the fundamentals of garage door cables, including how they work, assembling cables from raw materials, and troubleshooting when issues arise. Our company offers both pre-assembled and raw cables, along with instructional videos for cable installation or replacement.

 

Garage Door Cables Overview:

Garage door cables play a pivotal role in the operation of the door, wrapping around cable drums connected to the shaft. As the shaft turns, these cables lift the door. Whether you need raw cables or pre-assembled ones, we provide the necessary resources on our cable and fittings page.

 

Raw Cable Usage:

Raw cables, without fittings, are typically used by contractors for doors of varying heights and lift types. For standard lift doors, determining the cable length is straightforward—add 18″ or 1.5′ to the door’s height. However, doors exceeding 8′ in height may require different cable drums. Installers often carry precut cables for residential doors, cutting several lengths from one spool for taller doors.

 

Cable Assembly:

Commercial doors usually require an oval sleeve and two cable stops for each cable length. Residential doors typically have only one stop per cable. Cable crimpers and cutters are essential tools for assembling cables. Crimpers secure sleeves and stops onto cables, while cutters trim cables to the desired length.

 

Cable Assembly Instructions:

Assembled garage door cables have a looped end and a stop end. To create the loop, pass the cable through one side of the oval sleeve and back through the other. Crimp the sleeve to secure the loop. The other end, with the stop, wraps around the cable drum. The inside stop acts as a washer on the drum, while the looped end attaches to the bottom fixture of the garage door.

 

SSC Spring Engineering App:

Our SSC Spring Engineering app simplifies cable length determination. By selecting the drum used on the garage door, the app provides the cable length formula and the recommended cable diameter for that drum.

 

Other Uses for Garage Door Cables:

While the primary purpose of garage door cables is to support the door’s weight, they serve additional functions. Extension spring safety cables prevent dangerous situations by ensuring springs don’t fly off if they break. Some garage door locks also use cables to connect the latch to the handle and locking mechanism.

 

Cable Maintenance and Repair:

Over time, garage door cables may wear out or break. Cable repair is a critical aspect of maintenance and, when done correctly, is a swift process. It’s essential to remember that cables are under tension, and safety precautions must be followed during replacement. Our blog and video resources provide guidance on replacing garage door cables for both standard torsion spring and alternative systems like Wayne Dalton TorqueMaster and extension spring doors.
