With these concealed lead covers you can securely lead the cable from the frame into the leaf. Thanks to the covert design and installation on the frame side, the cable is inaccessible when the door is closed, so it is sabotage protected.
Version without casing.

Since the wire runs through a metal spiral hose, any cable damage due to rupture or clamping is out of the question.
For aluminium and plastic doors.

Stainless steel case and spiral tube.
