The Kodak Carousel Transvue 80 slide tray holds up to 80 1/16-inch slides--cardboard mounted only. Several easy-to-use, peel-away labels are included so you can identify and index your slides. The tray is translucent gray for easy slide-number identification. This tray isn't compatible with Kodak S-Series or Kodak Ektagraphic S-AV2000, S-AV2030, or S-AV2050 models.
Round slide trays are an integral part of the KODAK Slide Projector system. They are designed to accept standard 2" x 2" slide mounts.
