What is a corner brace used for?

What are corner supports called?
Corner supports are typically referred to as corner braces if they're designed to fit inside the corner of a joint. When they're designed to fit on the outside of a joint, they are usually referred to as corner irons.

Are corner braces necessary?
Corner braces are not always necessary for properly assembled furniture or carpentry projects that are already durable, but they can be necessary for furniture or other carpentry that needs to be reinforced.

How much weight can corner brackets hold?
Typically, corner brackets are not used to hold weight, but are used to reinforce a corner so that it is more stable and will not loosen over time. While they add some strength to a joint, they are not a substitute for other structural braces or brackets.
