Garage Door Accessories 2' Spring Fitting

Every torsion spring uses a stationary cone to keep that end of the spring from moving. The other end of the torsion spring uses a winding cone (pictured above) which secures the spring to the shaft. This cone applies the tension to the shaft and thus provides the lift for the garage door.

Torsion spring cones are primarily based on the inside diameter (ID) of the spring. A 2" set of torsion spring cones, for example, cannot be used with 1-3/4" or 2-1/4" ID springs. Another important characteristic of torsion spring cones is the wind. Left-wind cones, like the 6" winding cone pictured above left, must be used on left-wind springs. Likewise, right-wind cones, like the 3-1/2" winding cone pictured above right, must be used on right-wind springs. Some cones, like the 3-3/4" winding cone pictured above center, are considered to be dual wind - this means that they can be used with either left- or right-wind torsion springs of the corresponding inside diameter.
