Changing the Game in Remanufacturing
Columbus Castings offers the most unique, value-leading, and game changing Type H Tightlock Coupler remanufacturing process available to operators and owners of heavy rail passenger cars. We have developed the process to ensure that your used coupler is returned to you in like new condition with all wear surfaces returned to original manufacturer print specifications, all internal parts replaced, a new Type H Knuckle installed, and the coupler body magnetic particle inspected for safe operation. We are establishing a new industry standard for safety and effective maintenance at a fraction of the cost of a new Coupler Body.
Our unique remanufacturing process exceeds the requirements of the APTA Recommended Practice Second Hand and Reconditioned Type H Tightlock Couplers RP-M-004-98. For a summary of the features of our process click here.
