What it is
A single reel for Paterson and AP tanks. It adjusts for 35 mm, 4x4 and ordinary medium format — 4.5x6, 6x6, 6x7, 6x9.
What it fits
Fits Paterson and AP tanks — the same ones sold with a single reel. A second reel is what lets you develop two films at once.
One practical note
Load it dry, always: a damp reel jams halfway and the film has to come back out in the dark. Rinse it after processing and let it dry through.
