SL730 #7 .177 Wire 30" Lock End Extension Springs for One Panel Garage Doors
Determine your garage spring size- Examine the label at the end/s of your existing springs
- FIRST LETTER/S: these determine the securing mechanism or type of spring. A lock end springs label will start with SL
- FIRST NUMBER: this is the gauge of wire that the coil is crafted from. A 7 means 7-gauge wire
- SECOND NUMBERS: these determine the physical length of the spring
2. If your spring is missing its label- Get a tape measure or ruler
- Place sideways over the coil to get the diameter
- Place it lengthwise and measure the length of ten coils, then divide this number by ten. This will give you the wires size/gauge
