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.
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 GFI is a concealed door loop - mounted in the hinge line of the door, it is completely hidden when the door is in the closed position.
