Use the Hunter 12 in. Extension downrod black in rooms with 9 ft. Ceilings to maximize the cooling benefits of your Hunter Original ceiling fan. The downrod features a 3/4 in. Dia for stability and a debarred interior channel so the wires won't become stripped. Drilled holes in the downrod help you achieve the proper electrical grounding. All Hunter Original extension downrods match Hunter Original fans for fit and finish, and have tapered threads with double-threaded construction for deeper engagement.
