These large units contain six long slim boxes within a larger outer box and store up to 2,160 slides in easily identifiable groups, in either .065 MicroChamber/Silversafe board or .065 MicroChamber conservation board. Available for both 35mm and 2-1/4″ mounted transparencies, each inner box (slide tray) will hold up to 360 slides. 35mm boxes come with neutral pH, non-buffered alpha cellulose index tabs to separate slides into eighteen groups; 120mm boxes have tabs for thirty compartments. Note: the tabs are taller than the boxes, and are meant to be folded down when lids are placed on the box but will pop up to identify the groups of slides they separate. They also feature our corrugated insert follower block system, which uses slots to prevent slides from shifting in partially filled boxes. Full depth lids add extra protection, strength, and security.

For 120 mm slides: Outer boxes 19-3/8 x 21-1/8 x 3-1/2 (come with 6 inner trays); Inner trays measure 18-5/8 x 3-5/16 x 3-1/16 (inner boxes are also sold individually)
