Hörmann 751 tension spring for track application Z

Tension springs counterbalance the sectional garage door so that it can be opened easily by hand or by the operator. Spring no. 751 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 inside on the right, and also at the top of the spring on the roller holder. Hörmann tension springs are divided into Type 1 with one spring bundle and Type 2 with two bundles. Spring 751 is Type 1 – order it only if your original spring has one bundle and the number 751. Other Type 1 springs include 741 and 752. 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 do not wait after one spring breaks, replace both.
• Leave the replacement to a specialist – we carry it out in the Košice and Prešov regions; see the Service page.

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