RT Couplers

RT Couplers

Ancon RT threaded couplers are among the smallest in the Ancon range, best suited to large scale projects requiring a high volume of couplers. Their small size allows them to be used in places where a larger coupling system may not fit, such as at the end of cogged bars in thin panels.

RT Standard Coupler

The Standard RT Threaded coupler is suitable for connecting two bars of the same diameter, where one bar can be rotated. The ends of the bar are threaded for half the length of the coupler. Contact Ancon regarding situations where rotation of the continuation bar is difficult or impossible.

Bar Diameter 12 16 20 25 32 40
Product Code RT12 RT16 RT20 RT25 RT32 RT40

Testing
The Ancon RT system has been tested extensively in New Zealand using local and imported grade E, micro-alloyed reinforcing bar. Testing indicates that the RT system can meet strength, slip and cyclic slip performance criteria stipulated in the Concrete Structures Standard (NZS3101:2006 A3) and the NZTA Bridge Manual. Testing also suggests that variations in steel reinforcement materials, combined with cold-work production processes, may result in reduced ductility and ultimate tensile strength (UTS) in the spliced region relative to the performance of the parent material.
