LADDER BASE SUPPORT ASSEMBLY
A base support assembly includes a substantially vertical first support brace; a substantially vertical second support brace oriented substantially parallel to the first support brace; and a first cross member and a second cross member each extending between the first support brace and the second support brace, the first cross member crossing the second cross member to define an X-shaped cross member assembly; wherein: each of the first and second cross members are coupled to the first support brace by a first brace tensioning knob and coupled to the second support brace by a second brace tensioning knob; and each of the first brace tensioning knobs and second brace tensioning knobs are rotatable to tension the first and second cross members with the first support brace and the second support brace.
