The two-piece fastening element consists of a cable tie and a fir tree stopper, assembled together and ready for use. The fir tree fastening element is simply pressed into a pre-drilled hole, which can also be a blind hole. Several layers of lamellae ensure very good and secure fastening. The head of the fastening element also has a small plate that partially prevents dirt and water from entering the hole. Originally designed for the automotive industry to secure wiring harnesses, the product's simplicity and fast installation have found application in many industries, from aviation to switchboard assembly, and even in washing machine production.
