Garage Door Cable Drums
There are two cable drums on a torsion spring garage door setup. The cable drums are on the ends of the torsion bar and there is a right hand cable drum and a left hand cable drum. The door cables are attached to the bottom of the garage door and go up and around the cable drums. As the torsion spring on the garage door unwinds and the door opens the cables wrap around the cable drums.
There are different cable drums for
different torsion spring setups depending on how much headroom and how
high the door is. There are normal headroom, lift clearance and vertical
lift cable drums. We carry normal headroom cable drums. If you have a
normal headroom garage door that is 8' tall or shorter then you could
use the D400-96 Cable Drums. If you have a normal headroom garage door that's between 8'1" and 12'1" high then you could use the D400-144 Cable Drums. All of the cable drums we sell are sold in pairs.
