3:1″ punch format or 34 holes per A4 length. This is the Heavy Duty Electric version of the easy to use Renz Range. The best binding machine ever made in our opinion. Reliable, fast and easy to use. Able to punch and bind 3 x 20page documents in under 35 seconds. Wire is held firmly like a plastic comb but much easier so you can load the paper onto the wire. Punches 24 sheets at a time.

Renz Wire Machines are famous as the market leader and for shutting perfectly round every time holes to 1″ or 2:1″ is the only wire system that will bind documents from a few sheets to 300 pages without having to change the punch tool (5mm wire – 32mm wire). the wire by hand. Renz use a compact 5mm x 3mm punch slot which make even the smallest size as attractive as small size 3:1″. Other systems use the very large 6mm round or square holes which only really work on wires sizes 19mm upwards.

Highly efficient design layout uses vertical punching and once the paper is punched there is no need to change hand grip and the paper is simply brought forward onto the open wire binder and then simply pushed forward to be closed perfectly round and evenly. Punch capacity of around 25 sheets ensure the hole quality does not deteriorate. Has an adjustable margin depth gauge. Built-in gauge for measuring book thickness and wire size selection. Virtually unjammable due to the same mechanism and force that is used to punch is also used to retract the punches. Other machines fail badly on this point by using a weaker system to retract the punches, resulting in internal parts snapping. High quality hardened steel punching dies.
