The shutters use a hardware arrangement including two types of louver pins, a compression spring and a tensioning mechanism to adjust the frictional drag on the shutters. The hardware facilitates a procedure in which the frame and louvers of the shutter are fabricated and finished separately and then assembled. The same kit of hardware can be used to make virtually any size window shutter having movable louvers. The tensioning mechanism includes a threaded insert that enables adjustment of the frictional drag on the louvers without causing deterioration or damage to the shutter frame. | |
