End-tab Pressboard Guides are used to divide entire filing systems into smaller groups for quick identification. Blank tabs are readable from both sides to allow quick identification once you customize them. Guides are wider than standard end-tab folders so tabs stand out. 1/2" wide tabs with vertical style No. 8 are in the top position. End-tab guides include flat metal tab. Guides are made from 25 point green Pressboard with a high percentage of recycled material.
