Abstract: A method of installing a support member includes disposing a ground plate of a support member on a ground surface. The support member includes a lift assist component that engages with a bar connected to the ground plate. The method further includes adjusting a height of upper ends of the support member by actuating the lift assist component such that the upper ends of the support member are elevated or lowered.

Abstract: An apparatus includes a first strap including an upper end and a lower end. A second strap is disposed adjacent to the first strap and includes an upper end and a lower end. The upper and lower ends of the second strap correspond in position with respect to the upper and lower ends of the first strap. A base portion connects the first and second straps between the respective lower ends of the first and second straps. A height adjustment system includes at least one bar disposed adjacent to at least one of the first and second straps, and a lift assist component that engages with the bar. In an orientation where the first and second straps extend vertically with respect to a horizontal plane, a distance between the horizontal plane and the respective upper ends of the first and second straps is adjustable via engagement between the lift assist component and the bar.
