Abstract: A sensor frame assembly that includes a plurality of extrusion members removeably attached to each other defining a walk through frame assembly. The extrusion members have an outer profile and a hollow interior space. The extrusion members include a top portion coupled to separated side portions. Each of the plurality of extrusion members includes a length that is less than four feet when disassembled. Each of the plurality of extrusion members includes a rectangular sectional outer profile wherein one corner of the rectangular profile is truncated at an angle forming a mounting surface. The mounting surface is angled relative to an orthogonal side of the outer profile.
