How To Measure Garage Door Torsion springs:
First measure wire size
Step1: spring’s wire size can be determined by using many tools, calipers,
micrometer, or wire gauge are some of the ways However many do-it-yourselfer do not have these items available
therefore a common tape measure will work. Measure twenty and use the chart below.(important: measure the
broken or relaxed spring to get an accurate measurement)
Step2: Measure inside diameter of coil... chances are you have a standard 1 3/4" or
possibly 2"... for most residential doors.
Step3: Measure the length of the coil... (just the wire not including the winding cones
on the end).
So here is a standard spring measurement .218 x 1 3/4 x 28 two eighteen by inch and three quarter by
28. Now how about skipping the technical part........
Standard garage door springs that I use to give you an idea if your in the ball park....
.218 x 1 3/4 x 28 Non-Insulated 16'x7'
.225 x 1 3/4 x 28 Insulated 16'x7'
.234 x 1 3/4 x 32 Steel Back 16'x7'
If you want to use the same garage door torsion springs that you currently have use the spring chart below and
call us with your size, (714)453-9655.
Use a standard tape measure and use twenty coils on your spring to measure this one seems more accurate. By the
way make sure you measure the torsion spring that is relaxed already, the broken spring.
After you find out the size of your garage door torsion springs give us a
we will send the torsion springs to your front door.
Garage Door Torsion Spring Facts
Torsion Spring Fact #1: a torsion spring has three variable dimensions that can
change the applied force to your door. First would be the spring length.. Decreasing spring length increases the
applied force. Second, the inside diameter, when the Id increases the Applied force decreases. Third your garage
door spring wire size is directly proportional to its out put.. therefore if the wire gauge increases so does the
Torsion Spring Fact #2: Did you know that your drums actually reduce the
amount of torque needed from your torsion springs. So as you increase the diameter of the drums you reduce the
amount of torque needed from the springs.
Torsion Spring Fact #3 Your torsion springs effectively distribute there
applied force through both cables so for a 200 lb door you have approximately 100 Lbs of tension in each cable.
Q: I meticulously followed your plan for installing garage door torsion springs yet my door does not seem weightless and balanced.
A: a garage door that is to heavy or too light is a result of wrong torsion spring size or to
much or to little tightening of spring...make sure you measure garage
door springs properly.
Q: my garage door is making a rubbing noise as i try to lift it or put it down by hand.
A: Check that end bearings are intact and that all moving parts are lubricated. Drums should not
have any space between them and end bearing plate otherwise cables will contact door during travel.
Q: Do I have to change both torsion springs?
A: No, but it is better to jus change both torsion springs because the other spring might break
soon and then you have to take apart the torsion system again to change the second spring.
