- No heat applied, no upsetting, no thread cutting
- Through normal-temperature swaging, original stress-resistance in tension and compression force is ensured
- Concrete placement is easy thanks to the small diameter and short length of the coupler
- Couplers are available for dissimilar sizes on request
