<p>Adapters For a Variety of Connections - 4 Adapters (NOTE- 2 Adapters come already connected together but come apart easily)</p><p>Either use one adapter by itself or use any combination of the 4 by connecting them together to create an adapter that will fit your hose.</p><p> After 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.</p><p>We tested these on newer model vacuums and was able to come up with a combination that worked for most we could find. Both with older vacuums and newer ones measure your vacuum hose and attachment to check the size before purchase because we want you to be happy with your purchase.</p><p> ** 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 even glue the pieces together.</p><p>Use these to connect your power tools vacuum port to your hose in your work shop or with your shop vacuums, also can use with dust collection systems.</p><p> Please check the size first of your vacuum hose, also feel free to message us on Amazon and we will be glad to assist you any way we can.</p>
