Out guide set offers an easy way to mark where a file belongs. Simply slide it in place of the file you remove to mark the location in your file drawer. When you return the folder, the letter-size out guide identifies the correct spot to place the folder when returned. Not only do out guides make it easier to organize and locate files in file drawers, they can also subdivide files into meaningful sections with preprinted daily tabs. 1/2" tabs are printed with the numbers 1 to 31 and are 1/5 cut in five assorted positions. Indexed Top-tab Guide Set is made of heavyweight, 25 point green pressboard and made with a high percentage of recycled material.
