Review on Universal Shop Vacuum Hose Adapter - WORKSHOP Wet/Dry Vacs Vacuum Adapter WS25011A 2-1/2-Inch to 1-1/4-Inch for Enhancing Shop Vacuum Accessories by Edward Noble

Good for tools. After reading negative reviews about it not being suitable, it turned out that users were using it incorrectly. Now the Thais got an adapter, my suspicion was confirmed. The large end is perfect for an industrial vacuum hose (2 1/2") and the small end is perfect for my tools with 1 1/4" outlets. Looking at the photos from the negative reviews, some have tried to install this adapter. to the outlet of the vacuum cleaner where the hose is attached. It doesn't go there, it goes to the end of the hose where the jets go.
