Abstract: A bracing system, useable beneath the habitable structures of mobil homes and manufactured housing to render such structures secure from loss of support due to seismic events, includes a plurality of tubular braces which are connected to chassis beams of the structures and to foundation pads supported at grade at spaced locations below the beams. The braces include pairs of longitudinal beams of fixed length which are pinned at lower ends to the pads and slope in opposite directions upwardly below the adjacent beams to their upper ends. The braces include a telescoping transverse brace pinned at its lower end to a pad and connected to an adjacent beam at its upper end. Each transverse brace is continuously adjustable in length through a selected range of lengths prior to connection between a pad and a laterally adjacent beam, and is fixed at its as-installed length by a pin secured in holes drilled after installation through the concentrically overlapping tubes.
