The cranked pattern hook and band hinges are for hanging the door or gate flush with the frame or post. They are ideal for heavy weight, high use doors, gates, garages and stables in domestic and agricultural applications. Depending on the weight distribution of the gate, the top or bottom pin can be mounted upside down to prevent unwanted removal of the gate. NOTE: Doors/gates over 2130mm / 7ft height, should be fitted with a third hinge
