This electric comb closer is very easy to operate with either the dual foot pedal or table-top button to activate the binding process. Part of the GBC modular series the PB2600 is designed to stack on top of any GBC modular punch to create a compact punch and binding system. Will bind all document formats up to A4 and comb binding elements up to 51mm. User-friendly features such as the adjustable binding knob and the LED display help you to easily set-up your system for each binding job. GBC's new exclusive “no-flip” spine stoppers prevent large elements from flipping forward when the element is opened.
