This is a trestle support bracket comprised of a main member referred to as a bracket housing, which is coupled to the trestle cross-beam and a second member, referred to as the wedge. The bracket housing is a four sided, open bottomed, walled frustum with inside surfaces (ridged) as the opposing inclined leg contact walls. The wedge member has an included angle which matches that of the inclined, ridged surfaces of the bracket housing. When trestle support legs are placed in position in the bracket housing and the wedge member is inserted between the legs, a bolt passing through the central hole of the wedge member and engaging the central threaded hole of the bracket housing will, when tightened, firmly secure the legs to the housing in an absolutely rigid manner.
