Hörmann 3 mm wire rope for track application N, torsion springs

The wire ropes connect the bottom of the sectional door to the torsion spring assembly above the door. This part is for Hörmann Series 40 sectional doors with track application N manufactured from 1/9/1999. The pack contains two ropes with a wire diameter of 3 mm and thimbles, for the left and right sides.

Choosing the length according to door height

• 3040 mm rope – for doors up to 2250 mm high,
• 3780 mm rope – for doors over 2250 mm high.

The ropes are for doors with a leaf weight of max. 170 kg. Cable drums are not included; for track application N and L there are the left-hand and right-hand N, L cable drums.

What to bear in mind

• Track application Z with tension springs – you need a different rope for track application Z.
• Industrial doors – for Series 40 industrial sectional doors with track application N there is the 4 mm SPU F40 rope.
• Springs – choose torsion springs, for example R707, according to the marking on the spring label.
• Replacement – the ropes are under spring tension. We recommend leaving the replacement to a specialist. We carry it out in the Košice and Prešov regions, see the Service page.
