Hörmann L701/L20 torsion spring for track application N, L or H, left-hand wound

Torsion springs sit on a shaft above the door and counterbalance the weight of a sectional garage door so that it can be opened easily by hand or by an operator. Spring L701 / L20 is intended for Hörmann series 20, 30 and 40 sectional doors with track application N, L or H and is left-hand wound. It is supplied including the spring winding cone.

How to find the right spring

Each spring has a small aluminium tag at its end with a designation, for example L701. Older springs may have the designation L20 on the tag – in that case, order this spring too. Do not confuse it with spring L700 / L19. The spring on the other side of the door has its own designation, for example R701 – check it on the tag as well. Other types can be found in the Garage door spare parts category. If you cannot read the designation, write to eshop@saver.sk.

Safety

• Replace both springs – the springs are calculated for the same load. When one breaks, the other is close to its breaking point.
• A spring can break suddenly – so after one spring breaks, do not wait and replace both.
• Leave the replacement to a specialist – a tensioned torsion spring is dangerous. We replace it in the Košice and Prešov regions; more on the Service page.

When replacing the springs, also check the wire ropes for track application N.
