I have a four star just due to my application and not having the size I needed. I was using for an older round bale ring and they are a size too large. They do the job and would work well for the correct size pipe as well. A bit pricey but better than me having to build the brackets myself.

Good replacement for clamps on dog kennel. Mine were damaged by storm.Took damaged one to store did not have my size in stock so we ordered it.

It's exactly what I needed to replace one on my dog kennel that I have. The only thing I don't like about it is that it dosen't come with a wing nut. That's easily fixed by purchasing one, but that's an extra purchase.
