An adaptor to connect a Dyson vacuum cleaner to a Black & Decker Mouse Sander.
The Dyson vacuum head handle needs to be removed - it's real easy, it simply unclips, please see the photos. It was designed this way to reduce the weight on the adaptor and to make it a bit easier to use.
Both ends of the adaptor are tapered to give a snug fit. It works well, significantly reducing mess when sanding.
