These corner braces have two legs which come together at a 90° angle, forming an L-shape. Also called angle brackets, they connect to a wall or other vertical surface on one side while the other side protrudes horizontally to support shelves and other structures.

Mending plates are flat metal pieces with mounting holes cut into them. One part of the plate is fastened to one object while the other half is fastened to another to strengthen the joint, provide structural reinforcement, and connect two edges.
