This document serves as a specification and parts reference for the nVent LENTON T-Series Vertical Splice Kit, model RBT5101. Please note that this document is a supplement; for full installation procedures, safety notices, and technical requirements, you must refer to the official nVent LENTON Cadweld Rebar Splicing System instruction manual.
Product Overview
The T-Series vertical splice kit is designed to join rebar of the same diameter. The kit simplifies the ordering process and helps ensure proper component sizing. Components are generally one-time use parts, though pouring basins and crucibles are prorated based on their anticipated life.

Kit Components
Each T-Series splice kit contains the following essential parts:
- Sleeve: The primary connector for the rebar.
- Filler Material Kit: Includes filler material, packing, pouring basin ceramic insert and disk, and pouring basin ceramic guide tube.
- Pouring Basin: Used to contain the molten metal during the welding process.
- Pouring Basin Crucible: The vessel for the exothermic reaction.
Components can also be purchased separately if needed.

Common problems
This document is a specification sheet. Refer to the nVent LENTON Cadweld Rebar Splicing System instruction manual for full installation procedures.
Ensure the rebar diameter matches the kit specifications (16 mm, #5, 15M). If the deformation pattern or spacing does not meet specifications, consider ordering kits with extended sleeve lengths.
Before use
- Verify rebar diameter matches the kit (16 mm / #5 / 15M).
- Ensure all kit components (Sleeve, Filler Material Kit, Pouring Basin, Crucible) are present.
- Read the full nVent LENTON Cadweld Rebar Splicing System instruction manual before starting installation.
- Check that the reinforcing steel deformation pattern meets the minimum product specifications.
Specs in practice
- Filler Material Kit
- Contains the necessary materials to create the weld, including packing and ceramic inserts.
Images and diagrams
- The diagram on page 3 illustrates the assembly components and dimensions (L1, L2, H1-H4) for the splice kit.
Model compatibility
- Designed for splicing same-diameter bars.
- Extended sleeve lengths are available if the rebar deformation pattern does not meet standard specifications.
