LENTON INTERLOK Position Transition Grout-Fill Coupler



  • Designed to splice different diameter bars
  • Positional feature allows the threaded coupler end to telescope out to close a gap between forms and to allow alignment of the grout tubes
  • Over-sized cavity allows for greater field tolerance
  • Taper-threaded end helps prevent movement of the reinforcing bars and eliminate misalignment
  • Requires less grout than most competitive systems
