Exit guides put an end to lost folders by clearly marking where folders have been removed. Simply insert the guide into the file location. Pre-printed forms on the exit guide indicate what file has been taken, who is using it, and the date it was taken. Each side of the outdoor unit has 150 entry spaces. A red tab at the top of the folder and at the center 1/5-cut position makes for quick identification. 1/2-inch tall tabs are printed in reverse type. Guides are made of 18-point stock. SFI Certified.
