An 80KG left-side torsion spring is a heavy-duty steel coil engineered to counterbalance sectional garage doors. It winds tightly under immense tension to lift the door smoothly, either on its own for small doors or as a pair for double garages.
Technical & Visual Features
- Material: High-tensile, oil-tempered steel wire.
- Color Code: Features a red winding cone or a red/white stripe to indicate left-hand winding.

- Compatibility: Designed for standard 2.1m to 2.3m high garage doors weighing up to 80kg (or 160kg when paired with a matching right-wound spring).
- Operation: Winds downward during installation to lift the door and unwinds to lower it.
