You can also use the charts below to order a higher cycle spring and measure spring coils . Contact us during purchase with your length and the coil winding direction of the spring your ordering
          
Caution: Garage door springs are under extreme tension!!  We
recommend repairs, adjustments & removal to the springs or any
working part of the garage door to be made by a qualified door
technician. Any attempts to repair, replace, adjust are done at your
risk. We are not responsible (which includes any advice given) for
injuries, death or damages of any kind.

 If you have two springs on a residential or commercial door, it is 
 
critical that you measure both springs. Some of the manufacturers and service companies mix wire sizes. Follow the steps below to determine the correct dimensions.   
 
1.  First get the wire size.  All measurements must be taken 
 
off the unwound spring. On the unwound spring, count 10 coils Measure the width of those 10 coils.  
Then count 20 coils again on the unwound spring and measure . Using the chart at the bottom of this page . Take your 10 coil and 20 coil measurements and match it to the wire size shown on the right 
 
side of the chart .   
Note: 20 coil count is to double check your 10 coil count.
 
                                                 Next

2.  Measure the Inside diameter  of the old spring. 
 
(1.75" or  2" are the most popular sizes )
                                                Next

3. Measure the length of the coils of 
 
the unwound spring. (don't include the end cones) or any space between the broken spring coils. 
 
                                               Next

4. Determine if you need a (Right Wind Spring) or 
 
(Left Wind Spring). A pair of springs would include the right and 
 
left.

 ANSI/DASMA 103 (Door & Access Systems Manufacturers Association) Standard for Section Interfaces on Residential Garage Door Systems 
 
(spring winding cones are coded red and black.)

                           (Red)    right hand wind.
 
                         (Black)   left hand wind.
Check the diagram below to determine if your springs winding cones are color coded properly


Please note the side of door the spring is mounted DOES NOT 
 
indicate spring wind needed.  Standard garage door systems have the 
 
(Right-hand wind) red winding cone  mounted w/ the red 
 
winding cone pointing towards the LEFT.  The (Left-hand wind) black winding 
 
cone  will be mounted w/ the black winding cone pointing towards the 
 
RIGHT.


                 Determine the wind of your spring and place your order

                                  Torsion Spring Windings

Left Hand Wind       Right Hand Wind

                                       Check your installati 
on
When winding the springs..Wind in the direction of the coil. Right hand wind would be wound counter clock wise in this diagram above with the spring mounted on the left side of bracket.
2. Left hand wind would be wound clockwise in the diagram with the spring mounted on the right side of bracket.On a standard Garage door system and the springs are mounted above the door near the center you will be winding upwards.

 Caution: the following rules are for different spring configurations of garage door systems. If you have a low head room track or an older door system the springs could be mounted on the opposite side of the mounting bracket compared to a standard system. Always check the spring wind before removing your old spring to make sure you put the new spring on the correct side of the mounting bracket.
                          
To understand garage door lingo, you must picture yourself inside the garage looking out of the garage door. Anything to the right side of the garage door would be right side (part). Anything on the left side of the garage door is considered a left side (part).

**Before you remove the old springs, make sure they're both unwound check the color coding on the winding hub or the wind of the old springs and install the new springs in the same position on the mounting bracket.                                                                                                    
Standard garage door systems have 2 springs mounted  near the center above the door. Both springs will be mounted on one bracket located above the door near the center.The (right hand wind) red coded spring would be the spring mounted on the left side of the bracket and the (left hand wind) black coded spring would be on the right side of the bracket

Low headroom Garage door system (non standard), Spring configuration are Opposite and designs vary by manufacturers (like Crawford door systems)  
Cable drums could be  mounted outside of the ( end bearings) and
the springs could be mounted on the end bearing on either side of
the garage door (not in the center), the springs could also be
reverse mounted. Cable drums could also be reversed and raveling in the opposite
direction of a standard garage door system.

Some of the reasons why you need to know whether the coils on your spring are left hand Wind or right-hand Wind.

 1) Some manufacturers do not color code the winding cones.

 2) Sometimes the color code on the winding cone doesn't match the coil wind direction.

 3) Some manufacturers don't follow standard practice.

 4) The springs could have been mounted and installed incorrectly.

 Always check the wind direction of the spring coils before winding them
 


   Residential springs are wound at 1 revolution per foot height of your garage door. If you have a 7 foot high garage door and a standard 10",12" or 15" radius garage door track  with standard cable drums (400-8), you would wind your springs 30 quarter turns (7x4=28+2 = 30). This equals 7 1/2 full turns to the spring. The added 2 extra quarter turns are recommended so that in an imperfect system the cables won't unravel when the door is fully opened.It is strongly recommended that the spring shaft (End bearings) be replaced if they are not running smoothly. If there are signs of  black dust near the end bearings or near  the brace of the horizontal track, then the end bearings need to be replaced.  They could have been overheated  (caused by binding ,excessive weight and or usage)  they will probably fail before the next spring change.

If the rollers show signs of excessive wear, they should also be replaced.If you do not plan to replace the existing (end bearings) or (rollers),the rule of thumb is to add 1" to the length of the old spring size when ordering new springs. This will  lower the IPPTs (inch per pound turn) rating of the spring by about 1 increment.  It will also give you the flexibility to add an extra 1/2-1  full  turn to the spring during the winding installation procedure.  If these parts are not replaced  the system is not overhauled. Adding the extra turn will assure that the cables won't unravel when the door is in the fully opened position.
 The springs are almost completely unwound in the open position. There must be some tension left on the springs to keep the cables from unraveling. More spring tension is needed if the (end bearings} do not spin smoothly. Additional tension is also needed if the spring torsion bar is not perfectly perpendicular to the end bearings causing the end bearings to bind and wear prematurely. The spring shaft should be straight across (without a bow) or  the cables could unravel.

Do not wind springs more than 1 1/2 full turns over specifications. After winding the spring. 
Do not tighten the set screws and remove the winding bars without checking to see if the door springs  over wound , the garage door could fly open and throw you off your ladder. Ordering the exact size springs is very important. Before releasing the winding bars, and after you've put the full amount of turns to the spring(s) & have tightened the set screws,  gently move your winding bar up or down (depending on the garage door system). You should be able to feel the pull of the spring and the garage door movement. This is where you can determine  whether the door will go up by itself and knock you off your ladder. If it seems to be lifting on its own, the springs  are over-wound or the wrong rating for your door.

If the garage door starts to lift on its own,you need to unwind the springs & double check your  Spring dimensions and wind calculations. Then rewind your springs & check the spring fore again.  Caution: Never stand under the winding bars! Stand to one side or the other. Always have a good grip on the winding bars when tightening set screws.

~ WARNING~
   A well balanced garage door will will not move in the closed position and lift easily. Check the balance of your door by lifting it to 4 feet or about shoulder height. When released it should stay at that position or move slowly downward with no force. The garage door should not, at any position, drop or lift with Much force by itself. The
 garage door should not drop with enough force to crush a person's feet or damage the
 
garage door. The garage door should also move with Hardly any
 
upward Force as not to slam into the garage door opener or backstop. Check  that there is a  bolt on the end of both tracks to prevent the garage door from running off the track.
 


Caution:
Garage door springs are under extreme tension!!  We 
 
recommend repairs, adjustments & removal to the springs or any 
 
working part of the garage door to be made by a qualified door
technician. Any attempts to repair, replace, adjust are done at your 
 
risk. We are not responsible (which includes any advice given) for

Garage door installation and service companies mix spring sizes which include (Wire Size)(length)(inside diameter) and (IPPT Rating).
Single garage doors up to 12 foot wide usually require a (1) spring set up.
Double car garage doors up to 20 foot wide will usually have a (2- 4) Spring set up.

To understand the engineering principle of garage door torsion springs. The two spring or one spring garage door torsion spring set up can be considered the motor that lifts and lowers the garage doors.
 
The garage door opener is also a motor (electric). The electric motor is rated by horsepower as the springs are rated by IPPT. The electric motor should be adjusted to lift and lower no more then 10(LB) pounds to assure safe operation. The electric motor (Horse Power Rated) is only used to move the garage door up and down and does not actually lift the weight of the door. 

Springs are rated by the torque they deliver (IPPT) and can lift up to 500lbs for some residential doors.You can take any pair of Springs and convert them to a (higher cycle) or longer Life Expectancy. The sum of the IPPT rating for the original Springs must match the converted Springs. Let's say you have two Springs (.207 Wire size) x (2" Inside diameter) x (22" length) (.207x2x22). Each spring is rated at 24 IPPT equaling a total of 48 IPPT for the pair. You could can replace both Springs with two different (wire sizes) (inside diameters) and (lengths) as long as the sum of this IPPT rating is the same. 

Since the spring shaft rotates at the same revolution as the cable drums. You can install 1 or as many as 4 Springs on your torsion spring shaft and not affect the level of the door or the original engineered weight balance. The sum of the Springs you choose must equal the original IPPT rating.  Each spring can be a different (wire size)(inside diameter) and (length).

To replace your original Springs to a higher cycle use the charts below. If you have a .207 wire size and want a higher cycle spring. Match the IPPT rating with the .218 wire size of the same inside diameter to gain about 10,000 Cycles (up and downs) of the garage door. If you choose a.225 wire size in theory you should gain a additional 10,000 cycles totaling a gain of 20,000 cycles. Each wire size upgrade will lengthen the original spring length to equal the (IPPT) rating for the stronger wire coil.    


To determine the IPPT rating of your spring. Find the charts  below for (inside diameter) 2"ID  0R .175"ID (charts for.175 not yet in this listing). Then match your wire size to the corresponding row ,Find the length In the intersecting column to determine( IPPT rating / cycle life rating ) for the spring.require a (left or right wind spring).
