Product overview
Electric tightening for prepared rebar coupler connections
The SDX-400RLB applies electric drive to rotate and tighten already-threaded rebar and steel coupler connections. It is designed for repeated connection work in reinforced-concrete construction and infrastructure projects, helping reduce the manual effort required for coupler tightening. The tool tightens prepared connections; it does not cut, roll or create rebar threads.
