Kaiser K5023 Universal Clamp

Finally, a clamp that actually grips my enlarger column without slipping, even with a heavy timer attached. The rotating ball joint lets me position my focus finder exactly where I need it, and the build feels solid enough to last decades.

Perfect for holding my negative carrier steady while spotting prints, and the grip pads kept everything from slipping even on a polished workbench. Clamps onto different size tubes without leaving marks, which was my main worry before buying.

Took me five minutes to figure out the right tension, and now it's holding my timer and focusing loupe securely to a shelf edge in the darkroom. The clamp's grip is solid enough that I don't worry about anything slipping mid-print, even when I'm reaching around in the dark.
