There are three types of cable drums that correspond to three types of overhead-type garage doors: standard-lift, vertical-lift, and high-lift. Each cable drum is manufactured to help the garage door remain balanced as it opens and closes with the help of the torsion springs.
Standard-Lift Cable Drums
Standard-lift cable drums are flat for the most part. Toward the outside of the door, the last 3/4 of a turn or so on the grooves of the cable drum is slightly raised. This helps keep the garage door balanced as it begins to open.
Vertical-Lift Cable Drums
Vertical-lift cable drums are taller than standard-lift drums. When the garage door is closed, the cable is farther from the shaft. As the door opens, the cable wraps up on the drum and comes closer to the shaft
High-Lift Cable Drums
High-lift cable drums have both a flat portion like the standard-lift drums and a raised portion like the vertical-lift drums. The cable runs on the raised portion while the garage door opens vertically then switches over to the flat portion when the door begins to run on the horizontal track
