Choosing the Right Coupler System
Not every project needs the same coupler. RMS will help you match the system to the structure and site conditions:
- Choose TTS Tapered Thread couplers for fast, reliable installation where access is straightforward.
- Choose CXL Parallel Thread couplers for high-load and fatigue-critical work such as large-scale infrastructure.
- Choose MBT Shear Bolt couplers where threading the bar is not practical, for retrofits, extensions or congested reinforcement.
If you are not sure which system suits your design, send us your drawings and we will advise.
Applications
- Reinforced concrete beams and columns
- Precast connections
- Retrofit and extension projects
- Congested reinforcement or reduced lap zones
- Bridges, tunnels, and infrastructure works
Benefits of Mechanical Couplers
- Eliminate the need for overlapping rebar
- Reduce congestion and simplify detailing
- Enable full-strength bar development
- Speed up installation and reduce site waste
- Ensure code-compliant performance under tension, compression, and cyclic loading
Frequently Asked Questions
What size rebar do RMS couplers suit?
Ancon couplers supplied by RMS cover bar diameters from 12 mm to 32 mm. Detailed dimensions, weights and part numbers are available on request or in the technical datasheet.
Can couplers replace lap splices completely?
Yes. Mechanical couplers develop the full strength of the bar and are designed for tension, compression and cyclic loading, so they remove the need for overlapping rebar.
Does RMS install couplers, or only supply them?
RMS supplies couplers as standard, and can supply and install on request, depending on the project.
