Garage Door Spring Types

Garage door springs vary in sizes, depending on the height of the garage door and the weight of the garage door. Garage door springs install either above the frame of the garage door or on the rear end of the garage door track. All garage door springs serve the same purpose; they aid in the opening and closing of a garage door preventing damage to the garage door.

Standard Torsion Springs

Garage doors contain springs.

Standard torsion springs most commonly found on residential garage doors, mounted above the opening of the garage door supported by a shaft that runs through the center of the springs. One spring for lighter doors and two springs on the heavier doors, depending on the door size.

Easy Set Torsion Springs

Easy set torsion springs are very similar to the standard torsion springs. The difference is the hardware used to install the easy set springs. Standard torsion springs commonly mounted in the center of the torsion shaft. Easy set torsion springs mounted on each end of the torsion shaft, next to the cable drums.

Extension Springs

Extension springs are one of the most common springs and installed parallel to the garage door tracks on each side of the door. Extension springs work on a pulley system (with the cables of the garage door) wrapping around the pulleys. The other end of the spring attaches to an eyebolt mounted on the track.

Steel Rolling Door Torsion Springs

Torsion springs used for steel rolling doors vary in size depending on the size and weight of the door. Steel rolling doors commonly used in commercial buildings will have the torsion spring located inside of the torsion barrel that supports the rolling door.

One-Piece Curtain Door Springs

Curtain door springs have the same characteristics as steel rolling doors. Curtain doors commonly found on storage units, have springs visible when the door is in the open position. Curtain door springs attach on each side of the torsion rod that holds the weight of the door. Curtain springs secure with a set bolt on each end of the torsion springs. Curtain doors commonly have two springs; one on each side of the curtain door, located on the top of the door opening.

Torque Master Torsion Springs

Torque master springs specifically designed for safety. The torsion springs, enclose on the inside of the torsion shaft, and held in place using a winding cone on each end of the torsion rod. Torque master springs wind using a power drill, instead of, the traditional winding bar.
