The ¾’' Galvanized Flange is utilized with Premiere II Engineered High Peak Pole Tents only. The purpose of the flanges and nipple are to connect two fabric sections of the tent together; the nipple slides through the holes on the center plates connected to each fabric piece, and also through the O-Ring webbing extensions. Flanges are then attached to each end to hold all pieces together. The pin on the center pole slides through the center of the flanges and nipple.
