nVent LENTON Form Saver Anchor


The nVent LENTON Form Saver Anchor mechanical reinforcing bar splicing system provides a method of splicing reinforcing bar in segmental concrete construction applications that have limited space or are severely congested. The coupler is friction forged to the headed anchor/shear stud.

Typically used in wall applications, the nVent LENTON Form Saver Anchor easily attaches to the front wall form panel and fits into the wall reinforcement mat more easily than a hooked reinforcing bar. When the form is stripped, the protected threaded end of the coupler is exposed on the wall face. Simply remove the protective cap, install the nVent LENTON taper threaded dowel bar. This system eliminates hooked bar congestion, protruding dowels and the need to drill holes in expensive formwork.


  • The headed anchor/shear stud is C-1010/C-1020 AWSD1.1 and ASTM®-A108 compliant
  • Durable mounting plates allow for easy attachment to forms
  • Built-in thread cover or screw-in plug protects internal threads from concrete paste contamination
