Plain Battened Door
The Plain Battened Door is composed of battens (from 3/4 to 1 1/4 in. thick), ploughed and tongued in the joints with straight tongues (which should be painted before insertion) and nailed to three ledges 1 to 1 1/4 in. thick, usually with wrought nails long enough to come through and be clenched on the back side.
