Product Description

Reinforcing Bar couplerLapped joints are not always an appropriate means of connecting rebar. The use of Reinforcing Bar Couplers can simplify the design and construction of reinforced concrete and reduce the amount of reinforcement required. The strength of a mechanical splice is independent of the concrete which it is located and will retain its strength despite loss of cover as a result of impact damage or seismic event.Approximate dimensions for upsetting system:The system utilizes internally threaded couplers with simple threaded and is suitable for applications where the continuation bar can be rotated.
