6x4.5 Medium Format Slide Mounts (50 Pack) – Snap-Lock ABS Frames for 120/645 Film –...

SNAP-LOCK ABS CONSTRUCTION – Ditch the flimsy cardboard. Our rigid ABS plastic frames feature a secure snap-lock mechanism that holds your 645 transparencies perfectly flat and protected. Unlike paper mounts that warp in humidity, these engineered frames maintain dimensional stability for decades of archival storage. GLASSLESS ANTI-NEWTON RING DESIGN – Achieve optically pure projection and scanning without interference. The open-face glassless structure eliminates Newton Rings (rainbow distortion) and prevents moisture entrapment, ensuring edge-to-edge sharpness when digitizing or projecting your medium format slides. THE MOST POPULAR MEDIUM FORMAT – 645 gives you the perfect balance: 15–16 exposures per 120 roll versus just 12 for 6x6 or 10 for 6x7. More shots per roll, lower cost per frame, and the widest selection of cameras ever made for medium format. Mount your entire 645 archive with confidence. BROAD 645 CAMERA COMPATIBILITY – Precision-molded aperture fits transparencies from all major 645 systems: for Mamiya 645 Pro/Super/AF/AFD, for Pentax 645/645N/645NII/645D, for Bronica ETR/ETRSi, for Contax 645, and for Fuji GA645. One mount for every 645 camera ever made. PROFESSIONAL 50-PACK FOR SERIOUS ARCHIVISTS – Each compact 7×7 cm frame maximizes storage density in standard slide pages and binder sleeves. Whether you are digitizing a vintage wedding portfolio or building a museum-grade archive, this bulk set delivers consistent, uniform protection across your entire 645 collection.
