The range of door loops from CDVI offer a safe and secure method of transferring cables from a fixed point (door frame) onto the door leaf. 
The range varies from the economical “Flex” through to the CDL concealed unit. All models have a metal loop for better protection, and all have a minimum internal diameter of 7mm which is sufficient to handle the most common cables used in door locking/control. 
The GF60 (ADL) is an external door loop with the “Diax” anti vandal fixings and screws. Ideal for problem areas and harsh environments.
