Twin Loop Bindings

Twin Loop Binding gives your documents a well polished look while keeping pages in perfect register. This tamper-proof binding system also lets your books open a full 360 degrees and allow your document to lay flat when opened. It comes in two different varieties, 2:1 pitch refers to 2 holes per 1 inch and 3:1 pitch refers to 3 holes per 1 inch. Different punching dies are needed for each of these styles and will depend on how large the books you are binding will be. 2:1 pitch Twin Loop ranges in sizing from 1/4″ (25 sheets of bond paper) up to 1 1/4″ (230 sheets of bond paper). 3:1 pitch Twin Loop has sizes ranging from 1/4″ up to 9/16″ (90 sheets of 20lb bond paper) or 5/8″ in Black only (110 sheets of 20lb bond paper). Twin Loop is available in 10 different colours.
