The OXO Good Grips Over The Door Side-by-Side Double Hook automatically adjusts to fit neatly over thin and thick doors (1 3/8” – 1 3/4”). A soft, non-skid surface protects the door finish and 2 non-slip hooks grip items securely. The Over The Door Side-by-Side Double Hook is perfect for bathroom, closet, laundry room, mud room, pantry or dorm. For best performance, use the Hook where there is a standard 3/16” gap between the top of the door and its frame.
