I have attached a picture of a pocket door in a current project.
Can you spot what's wrong with it?
If you look at it closely, you will see that there is a frame that is painted in gray and the center is in white. That's what the designer picked, it isn't the wrong part.
The two vertical gray sections of the door are called stiles. The horizontal parts are called the rails.
The stiles are not the same. They should be.
You can see that the left is bigger than the right. This is a mistake. A mistake that could be avoided with a clear set of drawings. They should be equal width.
If you do drawings, plans, blueprints, shop drawings, etc. this is the place for you.
Come by and take a look.
