So I know you're buying unattractive clips, but I'd like to say they look a lot bigger in the product photo. The photo is larger than the real clip. At this price I was surprised to see so few of them. However, I have verified that the opening is wide enough for my application. So if you're expecting big, strong brackets, be warned. On the plus side, they are actually made from 304 stainless steel as advertised and appear to be durable. The only thing I'm not sure about is the round disk that presses against the surface. I'm not sure how durable this part is. This is most likely the part that fails, if there is one. Only time will tell PROS: - 304 - Durable (for now) CONS: - Seems a little pricey for the size. They also lowered the price right after purchase so it looks like I paid too much. The round disc could be a weak point, but that's unclear at this point. SUMMARY: I am not happy enough to recommend this product. If you really need a 304, you might need a small clamp and can't find a competitor.
