FLEXIBLE is the key word here. Only need about 6 feet for my overarm blade guards on my sliding t.s. and my cabinet saw. I prefer good quality hose,the piece that I am currently using is great quality but to stiff. I have a sharkguard on my Unisaw and the current hose impairs it's ability to move up-down over wood easily. None of my usual local sources have what I need,3'' seems rare as I have found 2.5'' at several places. Any help would be appreciated.
