Hi, I need to join two 5-gallon buckets by their open ends.

Does anyone know of a clamping ring with over-center toggle clamp that would hold them together? I need to be able to part them easily for emptying the bottom bucket.

The buckets have a lip about 1/4" deep to the outer surface and 1/4" thick. Seems like a ring of 1/2' U-shaped stuff and a clamp would do it.

Thought I'd get the collective wisdom of you guys first before reinventing a wheel.

Thanks

Not knowing the application, vibration, leakage requirements...

Hook a long bungee cord in the bottom buckets bail holders and stretch
over the top bucket...
