As mentioned in other reviews these clamps fall short when it comes to attaching a 2" pipe on all four sides ( see photos for a perfect example). Unless you want to create a seal (which might look bad in some situations like mine) you're better off buying another strap that actually fits the 2" pipe. Aside from the sizing issue, I'm very impressed with the quality of these straps. Yes, they are a little flimsy, but that shouldn't be a problem for most uses.
