A truss hinge that allows hinging between truss parts, and also allows configuration into a different size, and spreads the angle of the truss open ends. One embodiment uses a first plate, having a connection part to a first truss, where the connection part is adapted for connection to a first truss. A second plate is movable relative to the first plate. The second plate also has a second connection part adapted for connection to a second truss. An angle setting part forms a connection between the first plate and the second plate, that holds the first plate relative to the second plate at any of a number of different relative locations between the first plate and the second plate. The plates include angle markings to set the connections.
