Finally, a center column that holds reels securely without any wobble during agitation. The agitator works smoothly for gentle, non-inversion mixing, which is perfect for my technique. This little piece has made my developing process much more consistent.

Didn't realize how much light my old setup was leaking until I swapped this in — the seal on this column actually blocks it out properly. The agitator works great for non-inversion agitation too, no more worrying about spills mid-process.
