FIT-UP PRO offers a complete range of tools engineered to simplify pipe alignment and flange fit-up while improving safety, accuracy, and efficiency. From spider pipe clamps and other alignment clamps that reduce setup time, to two hole pins, flange alignment bolts, and stepped wedges that streamline precision work, each tool is built to boost productivity. Our selection also includes framing squares and protractors for reliable layout, as well as manual and hydraulic flange spreaders designed to ensure safe separation and preparation for re-fit. Together, these tools give fabricators, welders, and pipefitters the confidence and consistency needed for high-quality results on every job.
