Battens are usually 10 cm to 15 cm wide and 20 mm to 30 mm thick. Ledges are usually 10cm to 20 cm wide and about 30 mm thick. Usually, the top ledge is kept 10 cm to 12 cm wide whereas the other two are made about 18 cm to 20 cm wide.
The length of the battens is cut as per the requirements of the door height. Door shutter is developed by joining series of battens by means of tongued and grooved joints and held together with the help of ledges. The shutter is hung either by iron T-hinges or cross garnets on the ledges.
