Euro Style Key Switches
Euro style key switches allow the fitting of a standard Euro style key cylinder. This permits common key suiting systems to be used.
These devices are constructed from high quality stainless steel and are available in standard or slim styles.
Door Loops
CDVI door loops are required when installing an electric door lock door side. They permit the connection of power across the door frame into the door.
Many types are available from simple low cost surface loops to concealed types that are installed on the hinge side.
Door transfer contacts are also available that make electrical connections from the frame to the door at the hinge side simple. They are available as two and three contact versions and are suitable for both fail safe & fail secure electric locks.
FLEX Door Loops
The new low cost FLEX door loop from the CDVI Group boasts cast 
aluminium ends with a stainless steel armoured cable. The low cost nature with features associated with much more expensive door loops makes this the first choice. The FLEX metal door loop is ideal where power is required to travel from the frame side to the door itself. This useful when using on the door electric locking solutions. The door loop is available in 30CM or 60CM length options with the same high quality features. The FLEX even features metal screw caps to hide the screw fixings that are also provided.
