Garage door in many cases will dictate how many springs are needed for your garage door if the garage. The garage door has one or two springs nested inside of the shaft. Doors with one spring place more pressure on the single spring than doors with two springs. In most cases on double door 16 feet wide and larger we recommend replacing with a two spring system.

Typically using a single spring instead of two will save just two or three dollars.
