ROFU 10318-7 1/4” Door Cord, 1/4” Inside Diameter

A door cord is the flexible loop that carries low-voltage wiring from the frame into the door leaf, so power and signal reach an electrified device in the door (electric strike hardware, contacts, electrified locking) without the wire flexing bare every time the door swings. The ROFU 10318-7 is the 7-1/4 inch cord with a 1/4 inch inside diameter, sized for commercial openings.

One configuration only. The 10318-7 is a single model, 7-1/4 inches long at 1/4 inch inside diameter, so there is nothing to select when ordering. If you need a longer loop or a larger bore for a heavier conductor bundle, you are looking at a different model number, not an option on this one.

No. An electric strike mounts in the frame, so its wiring stays in the frame and never crosses the gap. A door cord like the 10318-7 is for power going into the moving leaf, an electrified lock, exit device, or a contact mounted on the door itself. If nothing electrified sits in the door, skip the cord.

Commercial. The 10318-7 is a commercial door hardware item, which is the relevant distinction for a property manager or integrator wiring electrified hardware in an office, multi-family, or institutional building rather than a house.
