The Add-A-Leg Bracket many times is used in place of a ‘T’Bracket. The difference is that a ‘T’ Bracket must be installed with the main frame structure. The Add-A-Leg Bracket can be added after the main frame structure is complete. It is ideal for creating a zipper door opening. It can also be used to create a vertical or horizontal beam to hang pictures or ribbons, etc. See item 5 in the illustration to see the use of this bracket.
