Garage Door Springs

Sectional Garage Door Extension Springs Sectional garage door extension springs are the more common type of extension springs installed here in the United States. These springs stretch above and parallel to the horizontal tracks on each side. They counterbalance the garage door by pulling on the cables. As the door closes the door weight is transferred from the tracks to the cables, and the door it gets heavier, but the springs are also stretching and pulling against the cables to balance the door and make it easier to operate. The back end of the extension spring connects to an open-eye bolt or an s-hook, which connects in turn to angle iron or the garage frame. This spring uses a wire as a safety cable.Residential garages almost always utilize two springs, one on each side of the door. One end of each spring usually connects to an open-eye bolt. This bolt usually fastens to the angle iron that holds to track or to a beam in the garage frame. The other end of the extension spring connects to a pulley with a pulley fork.A pulley typically attaches to the other end of the extension spring with the help of a pulley fork. One end of the cable that goes over this pulley is attached to a cable adjustment clip. An S-hook attaches to this clip, as well as to the horizontal track. The other end of this cable rolls over a second pulley and down to the bottom fixture on the bottom section of the garage door. While one end of the cable attaches to the bottom fixture, the other end attaches to a cable clip. An S-hook secures this clip to the track.Do you have sectional garage door extension springs?

Commercial and industrial overhead doors have an extension setup very similar to residential garage doors. On heavier doors, there may be a special kit that connects the ends of multiple extension springs. This allows two or more springs to be stretched simultaneously on each side of the garage door. Not all commercial and industrial garage doors have this setup installed. Some still just use one extension spring on each side. For the most part, though, the rest of the system functions the same as with residential doors. Pulleys supply lift in both types, though commercial pulleys tend to be a lot stronger and capable of lifting heavier doors without premature breakage.

Garage Door Springs

One-Piece Garage Door Extension Springs Just as the name implies, One-piece garage doors operate as one large piece. When the door opens, the top moves inside of the garage, usually on tracks, while the bottom of the door rises outside of the garage. Extension springs pull against a pivot pin or a connecting point to counterbalance the weight of the door. Since the bottom of the door moves both toward the inside and outside of the garage, weatherstripping this type of door in not feasible. As a result, one-piece garage doors are more popular in climates less prone to harsh weather. One-piece garage door systems use extension springs to counterbalance the door. These doors typically use one or two extension springs on each side of the door, for a total of 2 or 4 springs on the door. The bottom of the spring is secured to an adjusting bolt which is fastened to a door jamb bracket. The top of the spring has a loop or a clip positioned over a large pivot pin or bolt. The springs stretch upward, nearly perpendicular to the garage floor. The other end of the spring attaches to a lever arm. The lever arm is attached to the garage door. As you open the door, the extension spring shortens and loses some of its stretch. Do you have one piece garage door extension springs?

Standard Torsion Springs Standard torsion springs, pictured here, are secured to the spring anchor bracket and rotate a metal shaft with a 1″ outside diameter.Standard torsion springs are the most common residential torsion springs in the garage door industry. Residential garage doors typically use either one or two springs. On a lighter garage door, one spring will suffice. In that case, the torsion spring may be mounted to the spring anchor bracket in the middle of the shaft above the garage door. Other times, the spring has an offset mount, meaning that installers do not mount the spring anchor bracket above the center of the garage door. If two torsion springs balance the garage door, they are typically mounted to the spring anchor bracket above the middle of the garage door. Having two springs on the garage door tends to make it safer, especially if one spring breaks when the door is open. The other spring will then keep the garage door from falling and injuring a person or causing damage to the garage door or other property. Does your door use standard torsion springs?

EZ-Set Torsion Springs Clopay EZ-Set Torsion Spring System: The white plastic shaft retainer holds the shaft next to the cable drum, which sits next to the winder.EZ-Set torsion springs appear very similar to standard torsion springs, but the hardware is quite different. Door installers mount EZ-set springs to winders on the ends of the shaft, which is also 1″ in diameter. The black winder has the letter “R” or “L” on it, corresponding to the right or left side of the garage door. As with standard residential torsion springs, typically one or two springs fit on the shaft. While most two-car garages will have two EZ-Set torsion springs and single-car garages only one spring, this does not always hold true. Some lighter 2-car garage doors only have one EZ-Set torsion spring. In this case, the spring is usually mounted on the left side of the garage door. Clopay EZ-Set shaft support bracket.Some of the wider garage doors have two shafts with a coupler in the middle to connect the two. This extra piece of hardware can save you a lot of time and trouble replacing your EZ-Set torsion springs in cases with very little space between the end of the shaft and the wall. Double-car garage doors, with either one spring or two springs, will have a center support bracket (pictured). Single car garage doors will not have this bracket–typically nothing supports the middle of the shaft. Does your door use EZ-Set torsion springs?

Steel Rolling Door Torsion Springs Steel rolling doors are not made of sections like most garage doors. Instead, they join together by interlocking slats, which allow the door a greater range of mobility as it opens. With the extra mobility available, the rising garage door wraps securely around a barrel. Secured inside the barrel is a torsion spring. The spring counterbalances the door weight to make the door easier to operate. The barrel remains closed on both ends, so you cannot see the springs inside. While many doors only have one spring, some heavier steel rolling doors use multiple springs to balance the extra door weight. The barrel comes equipped with two head plates, located on each side. Two pieces of shaft pass through a bearing in the head plates and into the barrel. Inside the barrel, idler brackets support the shafts. Pins or screws fasten these brackets to the barrel. The shaft supports the torsion springs. One of the idler brackets serves as a spring anchor bracket to anchor the torsion spring. The other end of the spring typically has a cone that is secured to the shaft with setscrews, though some springs have a special loop at the end that is secured to the barrel with a rod. One side of the steel rolling door has a winding unit. A piece of angle above the winding wheel is secured to the head plate. This supports a bolt that rests inside the winder to anchor the shaft. You can adjust the spring tension by inserting a winding bar in another hole in the winding wheel, pulling down on the bar, and removing the bolt to free the wheel and shaft to turn. Spring tension is added by winding down on the winding wheel. A sprocket assembly connects to the shaft on the other side of the barrel. Installers typically attach an opener or a chain hoist to this assembly to operate the door. Do you have a steel rolling garage door?
