ABSTRACT:
A leg assembly for a trestle comprising a channel of an internal width to receive a lumber beam, which is hinged to a plate bent at an obtuse angle to form a depending panel shaped as a trapezoid. Means are provided to secure lumber legs to and along the edges of the depending panel to form A-frames which diverge with respect to each other because the steel panels to which they are attached are disposed at obtuse angles to the beam.
