Abstract

In one embodiment, a frame and stair system for engaging a wall includes multiple pad assemblies, a distal frame assembly, a lower proximal frame assembly, an upper proximal frame assembly, multiple stair assemblies, and multiple upper panel stair adapter brackets. A lower stair assembly is coupled with a left stair pad assembly, a right stair pad assembly, a left distal leveling pad, and a right distal leveling pad. A middle stair assembly is coupled with the distal frame assembly and the upper proximal frame assembly. An upper stair assembly is coupled with the upper proximal frame assembly. The upper proximal frame assembly is coupled with the lower proximal frame assembly. A left upper panel stair adapter bracket and a right upper panel stair adapter bracket are coupled with the upper stair assembly and are configured to engage an upper edge of the wall.
