Couplerbox Continuity Systems


The Couplerbox Reinforcement Continuity System is a combination of the Startabox perforated case assembly that can be provided with either the Dextra CARES Approved Rolltec Coupler or the CARES Approved Lenton Formsaver Coupler, in a single unit. Couplerbox has been developed to offer a rebar continuity system for larger bar diameters and where a high concentration of reinforcement or other factors prohibit the use of a rebend system, such as Startabox.


Couplerbox has the potential to be used in many concrete joints requiring a connection for reinforcement. It is especially suited and useful in applications where there is a requirement to fix many coupled bars and where climbing formwork systems are being used.

Some examples of its application are: -

  • Energy from Waste Facilities
  • Slipform Systems
  • Water Treatment Works
  • Diaphragm Walls
  • High Rise Construction
  • Composite Floors
