* Recommended torque for fatigue or earthquake loads.

Coarse tapered threads for robustness + fast and easy installation.
Easy and reliable visual quality control – no tool required.
Designed to transfer at least 700MP tensile stress. Thus the real stress and strain capacity of almost every spliced rebar can be used (no loss of ductility!)
Fulfils and exceeds all requirements of ISO 15835 “Reinforcement couplers for mechanical splices of bars” (including fatigue and earthquake classes)
Independently tested to comply with the requirements of:
- EN ISO 19903 “Petroleum and natural gas industries – Fixed concrete offshore structures”
- CSA N287.2-08 “Material requirements for concrete containment structures for CANDU nuclear power plants” (for tensile, compression and cyclic loads)
Successful tested at low temperature (-20⁰C)
Can be combined with other HRC products, as HRC 100 Series
Standard product length 200-15,000mm
