R-B Coupler is a parallel threaded mechanical splicing system designed for the connection of concrete reinforcing bars from 12mm to 40mm. The thread formed on the TMT Bar is by Rolling the thread on the bar instead of cutting the thread. This prevents the reduction of steel on the cross section area of the TMT Bar.

Only a single preparation equipment is required for this threading system. This system is recommended for projects in which the TMT Bars supplied are uniformly cylindrical.

R-B Couplers comply with BIS 16172, ACI 318, IBC 2006, BS 8110, Eurocode 2, DIN 1045 & ASME Sec III Div .
