Review on Premium Quality Beduan 1.5" Sanitary Tri Clamp - Heavy Duty 304 Stainless Steel - Pack Of 2 With Wing Nut For Ferrule TC 1.5 by Kyle Mason

Just awful. Flimsy to start, but what’s completely unacceptable is that they’re darned near impossible to use. A proper TC clamp has a wider gap on the inside edges and tapers to the outside. This gives you enough play to comfortably mount the clamp by hand, then as it is tightened, the narrower portion of the clamp is drawn into the fitting’s flange. These have basically no taper. On most fittings, I need to squeeze VERY hard by hand just to get it closed enough to swing the screw into place, which is even harder because the screw is too short for these clamps. Garbage.
