Choosing the right cord diameter for the gap width is crucial to ensure optimal protection. For a gap width of 16-20mm, a cord diameter of 30mm is recommended. Other cord diameters are selected depending on the gap width: for a gap of 21-30mm – 40mm, 31-40mm – 50mm, 41-50mm – 60mm, 51-60mm – 70mm, 61-70mm – 80mm, 71-80mm – 90mm, 81-90mm – 100mm and for a gap of 91-100mm – 120mm.

The roll contains as much as 50 meters of cord with a diameter of 30mm, which allows you to protect a large area. Remember to place the cord correctly inside the wall or ceiling – the surface of the cord should not protrude beyond the edges of the structure.
