The cable transitions from CDVI provide a secure method for connecting cables between a fixed and a movable point, such as a door frame and door leaf. The cable is protected by a stainless steel spiral hose. The inner diameter of the spiral hose is 9 mm, making it suitable for the most common multi-core cables used for door locking and control systems. The GF60 cable transition is mounted visibly, and the end pieces are secured with Diax screws, making it vandal-proof. It is suitable for challenging installations and harsh operating conditions.
