Hörmann L702 torsion spring for track application N, L or H, left-hand wound

Torsion springs sit on a shaft above the door and balance the weight of the sectional garage door so that it can be opened easily by hand as well as by the operator. The L702 spring is designed for Hörmann 20, 30 and 40 series 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 L702. Order a spring with the same designation. The spring on the other side of the door has its own designation, for example R702 – check this on the tag too. More 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; replace both.
• Leave the replacement to a specialist – a tensioned torsion spring is dangerous. In the Košice and Prešov regions we replace it, more on the Service page.

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