This is specific to a VacMaster vacuum which I use with a Dust Deputy.
The challenge was to fit the 15’ hose that came with the vacuum to the Sweepy. The photos show the parts used. One, the crevice tool, came with the vacuum. The other is a 1.5" O.D. x 3" section of soft rubber hose. The soft rubber provides the friction fit that makes this work. A piece of velcro strap holds the hose assembly to the router.
Vacuum connections for dust collection are notorious for their varying sizes but by chance I had the parts to make this work.
