Gibraltar SC-4425G Standard Clamp

I am amazed at the quality of this clamp especially because the the low price. I have used name brand clamps in the past and have had them slip on occasion. I have several of these clamps and they have never slipped. This is probably because of the fact that the adjustment nut is on the opposite face of from the tension wing-nut. There are other brands (some name brands) that have this same construction and they work just as well, however they cost more. In addition, because the tension nut and adjustment nut are on opposite sides of the clamp, it is easier to adjust them in tight places (like on a kit with many clamps/rods). You can't go wrong purchasing these clamps, they are an exeptional value.
