Garage Door Torsion Springs .234 X 2" X 27" ( Left or Right Wound )

Description

WARNING: Torsion springs, extension springs, and other garage door hardware can cause serious injury or death if not handled and installed properly.
Professional installation is recommended.
Do NOT attempt to install springs or hardware yourself unless you have the proper tools, reasonable mechanical aptitude and experience, and upper arm strength. Read and understand all instructions before you begin work.
Extension and torsion springs, along with attached hardware, are under extreme tension at all times. All tension must be released from springs before any work is performed.
How to Measure your Torsion Spring
This method of measuring your torsion spring requires you to measure the existing springs.  Use this method if the door worked correctly before the spring(s) broke and the garage door has not been tampered with.
To measure the torsion springs, follow each of the following steps carefully.  If the garage door has two springs measure each spring individually.  It is not uncommon to have two different size springs.
Step 1 Determine Springs ID (Inside Diameter)
For your broken spring(s) measure the inside diameter of the spring. If the spring is in one piece you can normally find the ID on the cones, P175 for 1 3/4" and P200 for 2". Typically residential springs will have a 1 3/4" or 2" inside diameter.
Step 2 Determine Spring Wind
Most standard residential torsion systems have two torsion springs, one on the  right and left.
The Left spring is right hand wound(RHW), and the right spring is left hand wound(LHW).
If one spring is broken on your torsion system, we highly recommend replacing both springs.
Step 3 Determine Wire Size
The most efficient
way to measure the wire size is to measure 10 coils and then measure 20 coils and compare the measurements to the chart below.  Measure to the nearest 1/16" of an inch.  It is important to make sure there are no gaps between the coils.  Measuring coils that have gaps will give incorrect measurements.
Step 4 Determine Spring Length
When measuring your torsion spring, remember that in order to get a proper measurement the spring must be un-wound. If the  spring is in two parts, unscrew set screws and connect spring ends together to  get a total measurement. Do not include the cones in the measurement.
