Hörmann R707 torsion spring for track application N, L or H, right-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 R707 spring is designed for Hörmann 20, 30 and 40 series sectional doors with track application N, L or H and is right-hand wound. It is supplied including the spring winding cone.

How to find the right spring

Each spring has a small aluminium tag at the end with a marking, for example R707. Order a spring with the same marking. The spring on the other side of the door has its own marking, for example L707 – check it on the tag too. Other types can be found in the Garage door spare parts category. If you cannot read the marking, 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 do not wait after one spring breaks; replace both.
• Leave the replacement to a specialist – a tensioned torsion spring is dangerous. We replace springs in the Košice and Prešov regions, see the Service page.

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