A cladding protection unit for a column of an adjustable support apparatus includes a frame including a first portion configured to be magnetically coupled to a second portion so as to extend around a perimeter of the column. Each of the first portion and the second portion include a sidewall. The sidewall of the first portion of the frame and the sidewall of the second portion of the frame form a column receiving space when the first portion is magnetically coupled to the second portion. A standoff flange extends outward from the sidewall. One or more magnets are coupled to at least one of the first and second portions of the frame. When the cladding protection unit is positioned around a perimeter of the column, the column is positioned in the column receiving space of the frame and the standoff flange of the frame extends outward from a perimeter of the column.
