This high-quality plastic organizer includes 15 removable dividers to create from 3 to 18 separate compartments. The compartments measure approximately 1 1/4" by 1 1/4" each when all 18 compartments are used, or approximately 1 1/4" by 8 1/2" when only 6 compartments are used. The latching cover keeps small parts securely in their places, even if the box is turned upside-down. Great for storing small items such as jets, fuses, and small fasteners. The "Zerust" dividers ward off corrosion of metal parts in storage. Box measures 9.125" long x 5.0" wide x 1.25" high. Made in USA.
