About this item

• Binding capacity: 30-165 sheets of 20# paper. The margin size affects the number of sheets that can be bound. For example, margins of 2.5mm for 165 sheets, 3.5mm for 155 sheets, and 4.5mm for 145 sheets.
• Pitch 2:1, 21-hole pattern and 3/4 inch (19mm); Color: Black.
• The wire coil can bind paper up to letter size. For smaller paper sizes, trim the excess wire with scissors or cutter crimper plier.
• Durable double-loop metal combs guarantee long-lasting performance. The metal construction doesn't warp easily, and paper doesn't shift easily during binding, making it the first choice for binding important documents.
• Especially binding using with Rayson TD1222 wire binding machine or any other 2:1 pitch binding machine.
