Ring binder
From Wikipedia, the free encyclopedia
Ring binders (British: file) are folders in which punched pieces of paper may be held by means of clamps running through the holes in the paper. These retainers are usually spring-loaded, frequently circular (some rings are D-shaped, others are actually rods), and may have additional latching systems.
Binders come in many standard sizes with respect to both capacity and paper size. Most countries use a two or four hole system for holding A4 sheets. The most common type in Canada and the United States is a three ring system for letter size pages (8½" × 11"). A standard 8½" × 11" sheet of paper has three holes with spacing of 4¼". The lever arch system is particularly useful for larger amounts of paper. Many personal organizers and memorandum books use a six- or seven-hole system, including Filofax, the FranklinCovey Franklin Planner, and Day-Timer.
Most binder covers are made of three pieces, in the fashion of a hardback book, but are produced in many styles. Materials vary widely. Some vinyl binders have a clear pocket on the outside for cover pages, and many have pockets in the inner cover for loose papers, business cards, compact discs, etc. There are also zipper binders, which zip the binder up and keep papers from falling out.
A popular ring binder brand is Mead's Five Star.
