Review on POWERTEC 70172 Hose Pipe Hangers by Seth Gibbons

I bought these to wall mount a 2 1/2 vacuum dust collection hose. I tried to put clamps on the hose, they didn't touch the wall. Even if I break the hose, they just aren't big enough. I thought it might be the brand of hose I was trying to install. I ordered a 20ft Powertec hose with these Powertec clamps, so I took the new hose out of the box and tried the clamps on it. The fit was even worse. You'd think Powertec could make hose clamps to match their own. hoses. I partly blame myself for not reading the negative reviews about these clamps not fitting the vacuum hose.
