Tapered Thread Rebar Coupler

Tapered Thread Couplers

Tapered Thread Couplers

Tapered Thread couplers are suitable for the majority of applications which require the joining of rebars.

They are normally supplied fitted to the end of the threaded bar and require only the engagement and tightening of the adjoining bar on site using a calibrated torque wrench.

Ancon Tapered Thread couplers are designed for use in concrete structures to meet the requirements of BS EN 1992-1-1: 2004 (Eurocode 2) and BS 8110 for mechanical splices.
