Plastic Binding Coils
Durability, Functionality and a Professional Finish
USI is your source for quality binding machines and supplies. Our rugged 12" plastic binding coils have a 4:1 pitch (4 round holes per inch) and glide easily through documents, givig the elegant look of a spiral notebook. Bound pages turn a full 360 degrees and bound documents are extra strong because of the multi-holes. You can crimp the ends of the coil for a semi-tamperproof document.
