High quality binding wires from Renz, for use with all A4 long edge spine binding (or A3 short edge, for calendars or landscape documents). Renz 3:1 wires are a closer loop wire than 2:1 pitch, with 3 loops per inch, giving a more attractive and secure final finish. 3:1 pitch wires are available from No. 4 (for just a few sheets of wire, or a calendar) up to No. 10, for up to 135 sheets of 80gsm paper. For anything above this size you will need to buy and use 2:1 pitch wires, which go up to No. 24 size.

Our customers have been using Renz wires for over 20 years and these high quality German-made wires have remained the industry standard for premium wire binding. All of the wire sizes and pitches, both 2:1 and 3:1 are also available on Renz spools of wires, speak to us about contract rates for these spools.

Renz wires are packed for extremely easy use - each wire is individually fixed onto a card sheet, eliminating tangles and mess, as seen in the video below.
