Questions and Answer # 1:

1. Should the base bid for ladder be 562 or 562-C? The 'C' in the part number indicates ‘cage’, so we wanted to clarify whether or not that was intentional, since there is a FP system on this ladder. Model 562 should be the correct number. Work statement has been amended above.
