Abstract
A corner (also known as angle flange) used to connect ducts together. The corner has an oblong or oval shaped button to help prevent rocking/play/loose movement thus providing a more secure/positive connection. A half moon squaring stop is used so that when the corner is inserted into a flange or frame, the corner cannot be inserted any more than a predetermined distance. Thus, the matching top and the bottom corners can be aligned properly and securely connected.
