“Knauf” double spring
The double spring is an element by which two bodies can be connected and thus increase the suspension height of the substructure. Through the optimal dimensions and the change in the ergonomic geometry of the rounded ends, the force required to deform the spring is significantly reduced. In this way, the wires can be easily inserted into the punched holes of the spring. The rounded shape of the spring ends minimizes the risk of injury. This simplifies installation and increases speed while maintaining high performance.
To extend the “wire with ear” system. It connects two bodies and at the same time allows for smooth height adjustment.
