Abstract

An adjustable, U-shaped support stand is disposed transversely between an expanded metal walkway and a roof so that the walkway may be made level although the roof slopes or may be inclined with respect to the roof. The support stand has a U-shaped base comprising a foot, a short leg and a long leg, each leg having spaced apart columns of holes. Connected to each leg are extensions having an oval slot and a hole spaced apart in accordance with the columns of holes on the legs. Alignment of the slots and holes in the extensions with the appropriate holes in the legs allows the extended legs to be of different heights with respect to each other and also allows one end of an extended leg to be higher than the opposite end. The expanded metal walkway may thus be levelled even though the roof slopes in both the lateral and longitudinal direction under the walkway.
