The SOUR CLAMP™ is a speed rail clamp that splits open so you can install it anywhere along the pipe — not just at the end. The inset 1-1/4" starter pin prevents spinning, keeping your rig locked in position. Machined from aluminum and built to handle real production loads on 1-1/4" pipe. One of those tools that solves a problem you didn't realize you had until you used it.
