2-Ring Binder Mechanisms (Box of 50)

Item #: 2RINGMECH-GRP

Used most commonly for top-binding letter size 8 ½" x 11" paper, as well as custom, unique binders, scrapbooks, and swatch books, our 2-ring binder mechanisms are a popular option. Made of a durable metal, these binder spines do not have any boosters, which means your sheet size is not limited. On each end are holes that allow you to use a rivet setter tool to set rivets, which is the most popular way to make ring binders. You can buy top bind letter size 2-ring binder mechanisms online in either 1" or 1 ½" ring sizes, and in round or straight-d ring shapes. The two rings on this ring binder hardware have standard 3 ⅛" spacing between the rings and are packaged with 50 pieces per box.

Capacity Chart

The best way to measure the capacity for a ring binder or ring binder mechanism is to use a stack thickness. To do so, allow your entire stack of paper, tabs, etc. to lay flat, without pressing them down, and measure the height of the stack. We also list an approximate sheet capacity, however, because there are so many different kinds of papers and paper thicknesses, this is a less accurate method of determining capacity. The sheet capacity below is based on standard 20 lb. copy paper alone.

1" 200 Sheets 5/8" Thick Stack
1 ½" 310 Sheets 1" Thick Stack
