Hörmann 765 tension spring for track application Z

Tension springs balance a sectional garage door so that it can be opened easily by hand or by an operator. Spring No. 765 is intended only for Hörmann series 40 sectional doors with track application Z, manufactured from 1999. Doors with torsion springs above the door have different springs.

How to find the right spring

The spring number is on the door's rating plate, located on the inside on the right, and also at the top of the spring on the pulley holder. Hörmann tension springs are divided into Type 1 with one spring bundle and Type 2 with two bundles. Spring 765 is Type 1 – only order it if your original spring has one bundle and the number 765. Other Type 1 springs include 764 and 770. If you cannot read the number, 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 – we can do it in the Košice and Prešov regions; more on the Service page.

When replacing, also check the wire ropes for track application Z and the tensioning wire rope holder.
