Hörmann R704 torsion spring for track application N, L or H, right-hand wound

Torsion springs sit on the shaft above the door and counterbalance the weight of the sectional garage door so that it can be opened easily by hand or by an operator. The R704 spring is intended 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 its designation, for example R704. Order a spring with the same designation. The spring on the other side of the door has its own designation, for example L704 – check this on its tag too. You will find other types 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 designed for the same load. When one breaks, the other is close to its own breaking point.
• A spring can break suddenly – so after one spring breaks, do not wait; replace both.
• Leave the replacement to a professional – a tensioned torsion spring is dangerous. In the Košice and Prešov regions we replace it for you; more on the Service page.

When replacing, also check the wire ropes for track application N and the spring breakage device.
