A method of, and apparatus for, handling a first die unit usable on a sheet extrusion system. The method includes the steps of: obtaining a carriage; placing the first die unit in a supported staging position on the carriage, the carriage configured so that with the first die unit in the supported staging position the first die unit can be moved guidingly around an axis; with the first die unit in the supported staging position, moving the first die unit guidingly around the axis to a desired angular orientation to thereby facilitate access to one or more identified regions of the first die unit; and performing an operation at the one or more identified regions of the first die unit.
