Master microfilm storage cases are available to hold several of the individual microfilm reel boxes. They meet all federal specifications for film storage. They have hinged lids which flip back and drop fronts to allow easy access to contents. These Master Cases are ideal for shelf storage, for they keep the small boxes neatly together. Both sizes will hold either 16mm or 35mm reel boxes. The 10in. long boxes hold either 6 reels of 35mm film or 11 reels of 16mm, and the 12in. boxes store either 7 35mm or 15 16mm reels. Offered in Lig-Free Type I or MicroChamber boards.
