I use little squeeze bottles for mineral spirits, denatured alcohol, etc. Refilling them has always been a messy and tricky operation while trying to hold the bottle, funnel, and canister all at the same time.
This little bottle holder has made that task much eaisier!! Having it clamp into the vise eliminates any possibility of the bottle tipping over.
Brilliant little tool. Do you have a French cleat wall? You can add a cleat to it.
