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 MicroChamber/Silversafe board or 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. These boxes also feature our follower block system, which prevents slides from shifting in partially filled boxes. Full depth lids add extra protection, strength, and security. Measurements are as follow:
