The adjustable length strut (25) includes an elongated strut plate (26) having a rectilinear C-shaped in cross-section support tube (32) and a mounting plate (36). An externally threaded rectilinear shaft (52) has its proximal end (56) inserted telescopically into the support tube (32). The threaded nut (62) mounted on the shaft engages the distal bearing edge (50) of the support tube, and rotation of the nut causes the shaft to distend from the tube for engagement with an I-beam (18) of the manufactured building structure. The chisel end (60) of the threaded shaft avoids rotation of the shaft with respect to the I-beam, so that rotation of the adjustable nut (62) provides accurate movement of the shaft out of the tube. The amount of the proximal end (56) of the shaft protruding into the support tube (32) can be visually determined by viewing through the elongated slot (42) of the support tube (32).
