The RDA FUB 40-40-60 NA Fit Up Bed System is designed to align two vessels during the fit up process prior to welding. Cost savings are realized, as it dramatically reduces the time and effort required for aligning and jacking cans. The system is designed and built to withstand harsh and rugged environments. Replaceable polyurethane tires are mounted onto cast steel drums for durability and superior traction. Optional steel rolls are available upon request.
