nVent LENTON Interlok Grout-Filled Precast Splicing System

nVent LENTON Interlok was engineered for use in precast construction. It is designed to provide structural integrity between load bearing precast concrete elements such as columns, beams, shear walls, and panels. nVent LENTON Interlok provides superior dynamic, seismic and ultimate strength performance for moment frame applications. Typical applications include column to column, column to foundation, shearwall to foundation, shearwall to shearwall, panel to panel, wall to floor slab and architectural panels.


  • Maintains structural integrity between precast sections
  • Provides load path continuity - reinforcing steel bars (rebar) act as one continuous bar
  • Tensile loads are transferred through the reinforcing bar independent of the compressive strength of the concrete
  • Helps eliminate costly and unsightly patchwork
  • Designed to meet or exceed building code requirements
  • Easy to use
