Innovative Rebar Coupling Technology
One-Two-Touch Rebar Couplers
Key Features & Mechanism
- Rapid Installation
- 1st lock: Easy bar insertion method as One-Touch Rebar Couplers
- 2nd lock: Hexagonal wrench tightening system to minimize residual deformation.
- Durability & Buildability
Combines advantage of threaded and One-Touch Rebar couplers enables single-person installation for labor cost reduction. - Compatibility
Our One-Two Touch Rebar Couplers are widely compatible with various rib patterns and standards such as ASTM, ISO 15835, and more.
