Cable Drum 8” (Left or Right) | Garage Door Hardware

Description Cable drums are essential components of a torsion spring garage door system. They are mounted on either end of the torsion shaft and are responsible for winding and unwinding the lifting cables as the garage door opens and closes. Each door requires a left and right cable drum, and they are specifically designed to be installed on one side of the shaft only — this helps maintain proper tension and balance. The 8” size is typically used for standard residential doors and is designed to support smooth and even lifting of the door panels, preventing misalignment or cable slack. Caravan Height Doors use a 12″ Cable Drum. Please make sure you order the right size. Sold individually. Please select left or right when ordering.
