Poly out guides offer 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 out guide identifies the correct spot to place the folder when returned. End tab in 1/5-cut center position and the bright red color make the out guide easy to find. Sturdy poly construction is acid-free, waterproof and tear-resistant. Each out guide also features two pockets - one for a sign-out card and a larger pocket to store documents that need to be filed in the missing folder.
