The range of door loops from CDVI offer a safe and secure method of transfering cables from a fixed point, such as 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 new “Flex” door loops have been introduced as extremely competitive units - newly designed cast aluminium ends with concealed fixings are features you would normally find on higher priced units.
