If you want to prevent a 5 gallon bucket from tipping or rotating, both the bail and the handle need to be immobilized. Having designed a non-rotating bucket handle, the next logical step was to make something that would prevent the bail from rotating.

After multiple failures I came to the realization that hardware was going to be a solution and added a nut and bolt to keep the "BailBoot" from splitting under load.

So far, this seems to work well; I can hang pretty heavy items from the rim of the bucket without it tipping over and spilling the contents.

The nut and bolt are 4mm x 25mm.

Fusion 360 file is included if you want to modify the design.
