Install one for a heavy 16x7 or standard 16x8 garage door. Two of these springs will lift a very heavy wooden or wind rated garage door. CAUTION- this spring size has alot of torque. Installer beware!
*Use the dropdown menu to select a single left side spring, a pair of springs, or just the one on the right side. When purchasing a single spring you must select left or right side. The correct orientation would be from standing inside the garage looking toward the garage door.
