The illustration shows proper lifter placement for a Round Ring binder. Note that two sheet lifters are used, and they are placed between the paper and the ring back, with the curvature facing inwards.
The next question is the size of the ring. Ring sizes are usually expressed in nominal inches. For example, 1″, 1.5″, 2″, etc. The table below lists the appropriate Sheet Lifter for each size of Round Ring Binders. Where more than one Sheet Lifter is listed, the top lifter is preferable.
