Installation tips Route the cable through the loop area so flexing occurs within the protector rather than on the cable insulation. Match loop placement to door hinge side and allow slightly more than 450mm of total cable run if additional slack is needed inside the door cavity. Inspect periodically for wear and ensure the protector remains aligned with door movement. What you get A purposebuilt 450mm door loop cable protector designed to improve the reliability and longevity of access control and video doorbell wiring without altering existing devices.
