I've been trying (and failing) to find a good way to dust all my tools. The connections I made depend on the tool as all the connections are slightly different and then the connection to the shop vacuum wasn't very good. This hose solved all my problems. The 2.5" plug fits my 2.5" plug perfectly and the quick release buckles are soft enough to fit snugly into all of my tool ports. I have an extra set of connectors to connect to smaller connectors like the .75" connector on my Makita random orbital sander. I have connectors that fit very well on my Makita random orbit sander, Makita circular saw and Dewalt table saw over the dust connector. It exceeded my expectations. I will definitely buy this again.
