An adjustable support bracing system for an upright structure includes a substantially vertical main frame (14) and a support plate member (16) pivotally secured to the main frame. The support plate extends on a first side of the main frame and provides supporting engagement of the upright structure. An adjustment device is connected to the main frame and bears on the support plate (16) for selectively pivoting the support plate to a desired support angle. An adjustable length leg (22) extends on a second side of the main frame opposite the first side. |
