AP “Compact” Auto Load Film Developing Reels feature a ball ratchet system for simple and fast loading. This reel is ideal for developing color and black & white films in formats 135, 126, 127, 120 or 220. Will also fit 828(35mm) and 620(120) format films. AP reels have a load gate to make the starting and rolling procedures easy.
This reel can be used in all AP developing systems, as well as Jessops, Kaiser and Paterson developing tanks.
The Brownie Camera Guy says:
AP tanks and reels are easy to use and don’t malfunction. Before rolling film onto the reel, make sure that the reel is completely dry.
