CXL Parallel Threaded Splice

Full strength joint with a compact coupler

CXL Couplers produce a full strength joint by enlarging the rebar prior to creating the thread, best suited to large scale projects requiring a high volume of couplers

  • The end of each bar to be joined is cut square and enlarged by cold forging. This increases the core diameter of the bar to ensure that the joint is stronger than the bar.
  • Parallel metric threads are cut onto the enlarged ends. The threaded end is then proof tested to a force of c.70-80% of yield strength of the bar.
  • The threaded ends of the bars are protected by an external plastic cap. Couplers, which are usually supplied attached to the bar, have their internal threads protected by an internal plastic end cap.
  • In some cases, the coupler end caps may not prevent the ingress of concrete fines. For these applications, further protection may be required.
  • Ancon CXL starter bars can be made to order to a specific length to suit the requirements of your construction project.
