Apparently Phantom poles 30ft and under use a smaller diameter No.1 section so no gardiners complete gooseneck will fit unless you modify it. Over 30ft they are leaving the No.1 section out and adding an extra section to reach the achievable pole length but still can't comment if Gardiners gooseneck will fit as I don't have one myself. I have asked before about the diameter or circumference of Phantom's 40ft pole but no reply from window cleaning warehouse on that or from Facelift. What I would like to know is where can you buy the inner sleeves for the clamps when they wear down as it's impossible to track where you can buy replacement sleeves.
