LENTON INTERLOK Position Grout-Fill Coupler



  • Designed to splice the same diameter bars
  • Smaller bars can be installed into the over-sized cavity end if required
  • 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
