The lift cable drums are made of aluminum compound and manufactured using die cast technique, which is a process of forcing molten metal under high pressure into a mold cavity. The standard 4.8’ cable drum (or pulley) is mounted to the door’s shaft by 2 locking bolts. The garage door torsion system has 2 lift cable drums, left (black) and right (red) and can lift up to 265 lbs. each, which equals to 560 lbs all together.

Once the garage door is lifted, the cables attached to the bottom of the garage door starting to wrap around the lift cable drums, keeping the garage door under balance while the torsion spring getting unwind.
