The IKS is a connection system that allows the risers to be connected to different parts of the wing, such as the lines or the harness. The IKS technology is a step towards greater lightness in wings and equipment, without sacrificing effectiveness and providing the same degree of safety and strength.

Niviuk has developed two types, the IKS1000 and the IKS3000, each one designed as a connection system for different parts of the wing:

- The IKS1000 is designed and dimensioned as a connection system between the risers and the lines.  It has a breaking load of 1055 kg, which greatly exceeds that of the classic 3 mm (550 kg) maillon, but with a much less weight.  This feature makes it a key element in the entire range of lightweight P-Series wings, which are delivered with this technology as standard. 

- The IKS3000 is designed to connect the risers and/or the parachute with the harness. Its breaking load of 2960 kg makes it an ultralight alternative to the 7 mm (3125 kg) maillon or an aluminium carabiner (2000 kg).  The IKS3000 design and concept make it ideal for mountaineering, hike & fly and ultralight equipment.
