Common uses include organizing documents, letters, magazines and mail in entryways or kitchens; holding phones and tablets in home daycares or classroom settings; and collecting student cell phones or other small devices during class.
Listings typically show hanging classroom organizers with either 36 pockets or 42 pockets (examples include both 36-numbered and 42-numbered pocket versions).
Some metal wall pockets include mounting screws and anchors for installation; certain acrylic or multi-part organizers note that adult assembly is required and that tools are not provided.
