ROFU 10320HD PCB Heavy Duty Stainless Steel Door Cord with Printed Circuit Board

The ROFU 10320HD is a heavy duty stainless steel door cord, the armored loop that carries low voltage wiring from the frame across the hinge gap into the door. It is what you run power and signal through for electrified hardware like electric strikes, maglocks, exit device power, or contacts, without exposing loose wire at the opening. The HD PCB version ships with the printed circuit board included for terminating the conductors at each end.

The PCB version includes the PC board. That is the only difference implied by the model designation, so if you are terminating to a board at the door and frame ends, ordering the 10320HD PCB means you are not chasing a separate part to finish the connection.

A surface mounted armored door cord like the 10320HD is the fast route: it screws to the frame and door face, needs no mortising, and can be added to an existing opening without pulling the door. A concealed electric hinge or concealed transfer device hides the wire but requires prep in the door and frame edge, which usually means new doors or a shop. If the opening is already hung and you need power at the door this week, the cord wins; if the architect wants nothing visible, it does not.

Yes. The door cord is the wiring path across the hinge gap, so it works with any low voltage device mounted in or on the door leaf, including electrified exit device power, electric latch retraction, door position contacts, and request to exit switches. The device itself determines conductor count and voltage; the cord just gets the wires across the gap safely with the PC board terminating both ends.

It is a commercial door hardware item, and the stainless steel heavy duty construction is what you want on a high traffic opening where the cord flexes every cycle. It is not intended as a light residential accessory.
