Movable dividers in this parts box allow compartment sections to be arranged and sized as desired. Three partitions- running from front to back- divide the box into four equal 4-1/2"x12" (114 mm x 305 mm) sections. Nine straight metal dividers can be positioned anywhere between the partitions- in one-inch (25 mm) increments- to create the compartments desired. Boxes feature strong- rigid- heavy-duty welded construction. Full-length piano hinged covers are designed to stay open for ease of access. Each box has a carrying handle- positive pull-down locking catch. Boxes have a heavy- metallic-gray baked-enamel finish. Box compartments feature high-impact styrene construction. Scoop-bottom design for easy parts removal and cleaning.
