With our 2-ring binder mechanisms, you can quickly and conveniently top-bind standard letter size pages that measure 8.5 inches wide and 11 inches tall, or really, any sheet size you need. Although that is the traditional size used, there really isn't a width limitation, since these are loose binding spines that don't limit you in that way. The spacing of the rings is standard for 2-hole punched documents, measuring 3-1/8 inches between the rings for easy compatibility. Use ring binder spines as a way to securely bind loose, hole-punched pages, or as a unique way to create swatch books and custom ring binders. You can pair with our binder rivets and rivet setter tool to bind the ring binder hardware onto a custom chip board sheet.
Two ring metal binder spines are available with either a 1 inch or 1.5 inch ring size in both round and slant-d styles. They do not have boosters on the ends, which really opens up the opportunity for your page width.
