A bi fold door top bracket is a frame that is placed at the top of a bi-fold door. It is made from wood, extruded aluminum, or steel and allows the operator to adjust the vertical angle because it has two flat sides
The bottom side of the bracket can be used to attach to the side of a door so that it does not sag when opening and closing. It also allows for adjustment for different door widths. This makes it possible to use this type of bracket on doors with different widths such as residential and commercial doors
The top side of the bracket has an L-shaped bracket that attaches to one end of the hinge pin on each side of the door. The other end of these hinges attaches to an upper hinge plate or header plate on each side that runs parallel with your wall studs (if you have them). Because these two sets of hinges are parallel and not perpendicular to your wall studs, they allow you to adjust your door up or down without affecting the overall height of your door opening by changing its placement over your doorway opening.
