These GBC binding spines are designed for clean, durable document binding with a flat-open finish. The 20 mm size is suited to books and reports up to 160 sheets on 20 lb paper, and the 4:1 pitch helps pages turn smoothly while lying flat for reading or copying. This 100-pack is a practical choice for offices, schools, and copy rooms using GBC ColorCoil equipment. The binding is permanent, so it is best for documents that do not need later editing or rearranging.
