Understanding Spring Direction
A left-wind torsion spring is wound in a counterclockwise direction when viewed from the winding-cone end.
On many standard torsion systems, the left-wind spring is installed on the right side of the center support bracket when viewed from inside the garage looking toward the closed door. However, installation layouts can vary, so always match the replacement spring to the original spring specifications rather than relying only on mounting position.
Compatibility
This spring is compatible only with garage door systems requiring all of the following specifications:
- .250-inch wire size
- 1.75-inch inside diameter
- 30-inch spring length
- Left-wind direction
A torsion spring should not be selected by door width, height, or appearance alone. The correct spring depends on the door’s total weight, drum size, track configuration, lift type, and required torque.
Even a small difference in wire size, inside diameter, length, or wind direction can significantly change the spring’s lifting capacity and operating characteristics.
How to Confirm the Correct Spring Size
Before ordering, verify the following information from the existing spring:
- Wire size
- Inside diameter
- Unwound spring length
- Wind direction
- Number of springs in the system
- Door weight or original spring engineering data
Measure the spring length only after all tension has been safely removed. Do not include the winding cone or stationary cone when measuring the spring body.
Package Contents
- One left-wind torsion spring
- One installed winding cone
- One installed stationary cone
Winding bars, center bearings, shafts, drums, cables, mounting brackets, and additional hardware are not included unless specifically stated.
Installation and Safety
Garage door torsion springs operate under extreme tension and can cause severe injury, death, or property damage if improperly handled.
Installation, adjustment, or removal should be performed only by a trained garage door technician using correctly sized winding bars and proper safety procedures.
Never use screwdrivers, extensions, ratchets, rebar, or improvised tools to wind or unwind a torsion spring.
After installation, the complete door system should be inspected and properly balanced before reconnecting the garage door opener.
