❓ FAQ

What does LHW mean?

LHW stands for "Left Hand Wound" – wound on the left. In double spring systems, it is mounted on the right side (viewed from the inside).

Can I install the spring myself?

Only with experience and the right tools. Torsion springs are under tension – assembly errors can be dangerous.

How do I properly care for the torsion spring?

The spring requires little maintenance. Occasional visual inspection for corrosion is sufficient. Lubrication is unnecessary thanks to the wax coating.
