What are Battens?
Battens are 3/4" stabilizing pieces of wood, attached to the back of solid wood doors such as the Valencia (81). They are designed to keep the door from warping or twisting. Battens are 1-3/4" wide and are placed 2" from the sides, 3" from the top and bottom of the door. This allows the door to be bored for hinges, while still maintaining its stability.
