Most file cabinet drawer dividers and inserts are made from natural bamboo or plastics. Common plastics used include polypropylene and PET (polyethylene terephthalate).
Expandable dividers commonly cover ranges around 17"–22" for standard drawers. Some sets are made for narrower drawers and expand from about 13.25" to 17".
Many sets include label stickers (often a 30-sticker set) and preprinted arrows to help identify compartments. These labels are commonly designed to be used with a chalk marker.
Expandable dividers typically use a spring-loaded mechanism combined with non-slip rubber pads. The spring locks the divider to the drawer width while the rubber pads help prevent sliding and protect the drawer surface from scratches.
Clear plastic trays are available in multiple sizes — examples include 2.9 x 2.9 x 2.1 in, 6 x 2.9 x 2.1 in, 9.2 x 2.9 x 2.1 in, and 9.2 x 6.02 x 2.1 in. They are easy to clean: simply wipe them with a damp cloth or rinse with water.
Drawer dividers and inserts are used to organize utensils and silverware, kitchen tools, office supplies, jewelry and small personal accessories, and clothing or dresser items.
Installation is simple and usually tool-free: many products use a one-click setup with a spring-loaded design, so you can expand or shorten the divider to fit the drawer without glue or tools.
Many bamboo dividers list a width of about 2.35" and a thickness around 0.6".
