I have used these same folders (No. 19882) for 30+ years. I am very disappointed with the newest stock of the folders I am now receiving. Smead has taken it upon themselves to move the prongs inside the folder in towards the center of the folder by 1/4" on each side. The "closeness" of these prongs to each other makes it impossible to put anything in the file more than 1/4" thick if you are using both sides of the folder - which I always do. I am very unhappy with the new design.
