Applications

35mm slide mount frames are used to house individual 35mm film transparencies or cut negatives for projection, archiving, or scanning. Once a film strip is cut, each frame is snapped closed around the selected image, bringing it to the standard 50x50mm (2" x 2") format that fits all standard 35mm slide projectors — such as those made by Kodak, Leitz, and Kindermann — as well as flatbed film scanners and slide digitizers. Plastic mounts like these have been used since the 1960s as a lower-cost alternative to glass-mounted slides, and remain in regular use today by photographers developing and archiving film, audiovisual departments maintaining legacy slide libraries, and educators or collectors digitizing historical transparency collections. Buying in bulk quantities of 500 is typical for working photographers, photo labs, schools, and archive projects with large volumes of film to mount.
