Adapters For a Variety of Connections.Five different adapters.á(NOTE- 2 Adapters come already connected together but come apart easily)Either use one adapter by itself or use any combination of the 4á by connecting them together to create an adapter that will fit your hose.á( the generic shop vac does not fit in to any of the 4 adapters, use by itself)áAfter realizing there are not really any universal adapters available we had these designed to fit the most common home vacuum cleaner hoses and then added a standard one which is the small adapter and the shop vac adapter to give plenty of options.á** Just a note if you combine more than one adapter to fit a heavier floor attachment you might need a piece of tape to hold it on, just because of the weight when you pick it up and down often.** You can also glue the pieces together.Use these to connect your power tools vacuum port to your hose in your work shop or with your shop vacuums, also can be used with dust collection systems.áPlease check the size of your vacuum hose, also feel free to message us on Amazon and we will be glad to assist.
