⚙️ Application & Assembly

The LHW torsion spring is installed on the right-hand inside of the door (in double spring systems). It precisely balances the weight of the door leaf and ensures smooth and safe door operation. Pre-assembly allows for quick and professional installation.

Safety tip: Torsion springs are under high preload. Only work with clamping tools (Ø 12.7 mm) and personal protective equipment (PPE). Disconnect the drive from the power supply before starting. Professional installation recommended.

🏁 Practical example

In heavily used garages, the LHW spring ensures even force distribution and protects the drive mechanism. Powder coating and wax film offer long-term protection against moisture and corrosion.

How long does a torsion spring last?

Depending on the load and care, it can last for tens of thousands of cycles – regular maintenance is recommended.

Which parameters are relevant when replacing existing ones?

The wire thickness, length, inner diameter, and winding direction are important. These must match the existing spring.
