From the entry level, right through to the heavy duty electric systems each comb binding machine has disengagement pins to allow you to choose whether you are going to bind an A4 / 8.5x11" or A5 / 6x8" document.
As well as this, each comb binder has an adjustable margin setting that provides various margin depth options.
The Magnum range of Comb binders can punch anything from 8 - 25 sheets at a time (based on 70gsm / 47lbs paper) and all comb binders will bind from 145 to 500 sheets, dependant on model.
You can be safe in the knowledge that each Magnum Comb binder in the range has a convenient waste paper tray to store the mess made from punching.
I know I can rely on my Magnum binder, it is reliable and gives us a professional finish.
