Unlike re-bend continuity systems where bar lengths are restricted to the box dimensions, there is virtually no restriction on continuation bar length with CB Coupler Boxes. Grade B500B or B500C continuation bars, threaded with a CXL metric thread, are supplied by Ancon in 12mm, 16mm, 20mm and 25mm diameter. The CXL system is CARES approved and produces a full strength joint.
Details of the standard coupler box range, along with installation guidance, can be found in the technical literature below.
