GBC WireBind spines with a 3:1 pitch and 34 rings are ideal for binding documents in A4 format. The wire comb diameter of 14 mm allows you to bind up to 125 sheets of standard 80 g/m² paper in one document. With WireBind spines, you achieve a particularly stable and durable binding that cannot be opened or manipulated. Wire binding, also known as wire comb binding, is a very popular binding method because it allows you to flip individual sheets up to 360°. When laid flat on a table, documents bound with wire combs, such as brochures or notebooks, will stay open. You can purchase GBC WireBind spines in packs of 100 at Schäfer Shop.
