Cast-In-Place Applications

nVent LENTON offers a variety of solutions for when cast-in-place is the specified method for your next project, with multiple choices for in-situ requirements.


The traditional method of connecting concrete reinforcing bars in high-rises, skyscrapers and towers has been lap splicing. But as many engineers and specifiers have discovered, lap splicing does not provide the same advantages as mechanical splicing in the reinforced concrete construction process.

We bring you the world’s most widely used threaded splices that create a positive locking connection and provide structural integrity to reinforced concrete slabs, beams and other building foundational elements. nVent LENTON spliced bars behave as continuous lengths of reinforcing steel bars by providing “full strength” in tension, compression and stress reversal applications to improve constructability and efficiency in major projects.

For construction business owners, the difference often comes down to time saved and money spent.

nVent LENTON Products and Solutions

Taper-Threaded Splicing Systems

nVent LENTON taper-threaded splicing systems provide a positive locking connection and structural integrity in reinforced concrete construction. Spliced bars behave as continuous lengths of reinforcing steel bars.

Mechanical Anchors

Mechanical anchors or headed bars are a replacement for hooked bars that greatly simplify reinforcing bar placement and reduce congestion.

nVent LENTON Connect

nVent LENTON Connect is an in-situ reinforcing steel bar splicing system that requires no bar end preparation. It is ideal for new construction, repair or retrofit applications and is designed for use in column splicing, bridge applications, piling, splicing to protruding dowels cast in concrete, closure pours, beams and other demanding splicing applications.

nVent LENTON Ultimate

The nVent LENTON Ultimate Splicing Systems and Mechanical Anchors are designed to maximize performance and shop efficiency as well as minimize installation difficulty in the field. Ultimate products are attached to the reinforcing steel using friction forging technology, commonly called friction welding.

Lap vs. Mechanical Splices

The benefits add up when you choose mechanical splicing connections for building reinforced concrete structures.

Lap Splices

  • Tend to have poor cyclic performance. To prevent concrete splitting, additional rebar may be required for confinement.
  • Present design constraints. Lap splices double the number of bars leading to rebar congestion, which can restrict the flow of aggregates.
  • Have hidden costs. Lap splicing can involve time-consuming calculations and overestimating mistakes.

Mechanical Splices

  • Are proven reliable. Mechanical splices behave similarly to a continuous piece of rebar and offer superior cyclic performance.
  • Are design friendly. Reducing rebar congestion and improving concrete consolidation are easier with mechanical splices.
  • Are economical. Mechanical splices require no special skills and reduce labor and material costs because less rebar is used.
