This is a common method of constructing cabinet doors and these are often referred to as a five piece door. In larger panels it is common to divide the panel into one or more sections. To house the extra panels, dividing pieces known as mid rails and mid stiles or muntins are added to the frame.
Bring water to just below a boil. Add eggs to steamer insert and steam for 15 minutes. Immediately transfer eggs to a bowl of ice water until cool enough to handle. Make a small crack on the large end of each egg and place eggs back into the ice water for about 20 minutes. Peel.
The best/only way I have found to hard cook fresh--1 or 2 day old eggs--that allows for them to be peeled cleanly, is to steam, not boil them. Put eggs in a basket over about 2 of water. Bring to a boil, cover and cook on medium heat so steam continues for about 20 minutes. Prepare an ice water bath as eggs steam. At the 20 minute mark remove basket and put basket with eggs in the ice water. Peel them in the ice water.
