Parts of your garage door
1. Garage Door Drum
The garage door drum is a part of a garage door’s torsion spring system, which helps lift and lower the door smoothly. The drum is located at each end of the torsion shaft, and its primary purpose is to wind the cables connected to the bottom of the door. As the torsion spring unwinds or winds, it rotates the drum, which then winds or unwinds the cables, helping to evenly distribute the door’s weight and ensure smooth, balanced movement. This mechanism reduces strain on the garage door opener and helps prevent the door from becoming misaligned.
