Simple, fast, safe reinforcement continuity strip for curved walls.
Coupler strip which offers all the benefits of the CB Coupler Box and is specifically designed to simplify rebar continuity at joints where walls are curved on plan. The flexible steel strip used to carry the couplers is nailed directly to curved shuttering.
The CS Coupler Strip utilizes the Ancon CARES-approved CXL mechanical rebar connection system. CXL couplers are integral to the CS strip and accept CXL parallel-threaded reinforcing bars.
The strip is cast into a concrete wall, and when the formwork is struck and the 6 mm rebate former and thread protection are removed, the CXL continuation bars are simply screwed into the CXL couplers when required on site, creating a strong, secure connection with the wall. The rebate fills with concrete when the next section is poured, providing a shear key in accordance with EC2.

Ancon CXL Continuation Bars:
Unlike re-bend continuity systems where bar lengths are restricted to the box dimensions, there is virtually no restriction on continuation bar length with CS Coupler Strips. Grade B500B or B500C continuation bars, threaded with a CXL metric thread, are supplied by Ancon in 12 mm, 16 mm, 20 mm and 25 mm diameters.
The CXL system is CARES approved and produces a full strength joint. The bar end is cut square and enlarged by cold forging. This increases the core diameter of the threaded portion of the bar to ensure that the strength of the bar is maintained. A parallel metric thread is applied to the enlarged bar end. A 12 mm bar is provided with an M16 thread, a 16 mm bar with an M20 thread, a 20 mm bar with an M24 thread and a 25 mm bar with an M30 thread.
