What does LHW mean?

LHW = "Left Hand Wound" – wound on the left. This spring is mounted on the right inside of the gate (in the case of double springs).

With correct installation and regular maintenance, it can achieve tens of thousands of cycles.

How do I find the right replacement spring?

The wire thickness, length, inner diameter and winding direction are important – these must match the old spring.
