Last year I asked my custodian to drill holes in the clip part and attach those big rings that are found on pocket chart holders. Those worked for a while, but I didn't like how bulky it looked. You might be able to see the drill holes in the photo above.
It only took me 7 years, but I finally discovered a solution!
Take the cover of the chart paper tablet (which is made of a thicker paper, almost like tagboard) and fold it up about 3-4 inches.
Hope my little tip helps and saves you years of being attacked by your chart paper :)
