Galvanized Round Quick Clamp  (also called clamp bands or flange clamps) are used on grain spouting and round auger systems where to round tubes with angle rings can be easily attached.  These grain spouting clamps are feature a lever system handle that allows for quick locking and unlocking of flanges.  The closing lever system is designed with a cotter pin lock to avoid accidental opening.  Locking and unlocking is performed with one hand and is ideal for tough to reach areas or where frequent maintenance is required.
