Parallel/ Tapered Re-Bar Couplers are designed to join the reinforcement bars. These Re-Bar Couplers reduce rebar congestion and improve concrete flow and consolidation. These Re-Bar Couplers are used for micro-piling, piling, slope protection, pre-cast concrete, slip-forming and formwork protection. Parallel/ Tapered Re-Bar Couplers are designed to join the reinforcement bars where at least one of the bars can be rotated.
