Ancon CB Coupler Box
Verified by manufacturer 6 months ago
Simple, fast, safe reinforcement continuity box.
Application
For designing slab-to-wall connections without the traditional restrictions on bar length and bar diameter of re-bend/ pull-out continuity systems.
Description
A coupler box which allows engineers to design slab-to-wall connections utilizing the Ancon CARES-approved CXL mechanical rebar connection system. CXL couplers are integral to the CB box and, once the thread protection is removed, accept CXL parallel-threaded reinforcing bars.
The box is cast into a concrete wall, and when the formwork is struck and the box lid and thread protection are removed, the CXL continuation bars are screwed into the CXL couplers when required on site, creating a strong, secure connection with the wall.
Features and benefits:
- Removes the traditional restrictions on bar length and bar diameter of re-bend/ pull-out continuity systems.
- Eliminates manual bar straightening on site.
- The steel casing remains embedded in the wall; a rebated dimpled surface provides an effective shear key in accordance with EC2.

Specification data - Socket anchors
Anchor length | 600 mm.Special order.Guidance for specification option: 600 mm length as standard or other box lengths are available. |
Thread diameter | 12 mm.16 mm.20 mm. |
End type | Guidance for specification option: 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. |
Threaded inserts | Guidance for specification option: 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. 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. |
Accessories | Ancon CXL Continuation Bars. Not required. Guidance for specification option: 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 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. |
