The Fellowes PB400 is ideal for anyone needing a binding machine that handles lengthy documents--up to 450 sheets and up to legal size (14 inches long). You can punch up to 20 sheets at a time, and the maximum binding diameter is a generous 2 inches.Although formidable in weight (over 40 pounds) and requiring some preparatory assembly steps, the PB400 is easy to set up and use. Two handles (one for punching, the other for binding) attach easily. We recommend following the simple instructions in the owner's manual, as misaligning the handles could bring your binding work to a standstill.
Among the more advanced features that are a part of this smartly designed model are disengageable punching dies and a binding lock dial. The former is variable to accommodate sheet sizes ranging from letter to A4 to legal; the latter is useful for binding multiple documents with the same comb diameter.
Overall, this Fellowes model is big and solid and built with an eye toward heavy usage, but it handles small jobs as well as big ones.
