Ancon’s range of Shear Load Connectors offers significant advantages over plain dowel bars. They are more effective at transferring load and accommodating movement and, due to their two-part construction, are more simple to install.
The sleeve component is nailed to the formwork and cast in with the first pour; drilling of either formwork or concrete is not required. Once the formwork is removed, the dowel component is pushed into the sleeve and cast-in with the second pour.
Ancon’s Shear Load Connectors range includes solutions for suspended and ground bearing concrete slabs.

The Ancon DSD is the original two-part, double dowel, shear load connector. The two dowels are Duplex stainless steel bar. The dowel component can move longitudinally within the sleeve to accommodate movement. The connector is available in ten standard sizes and has design capacities from around 20kN to over 950kN. The larger connectors can be used in joints up to 60mm wide. Larger joints can be accommodated using special dowels.
The Ancon DSDQ shear load connector uses the same dowel component as the Ancon DSD, but the cylindrical sleeve is contained within a rectangular box section to allow lateral movement in addition to the longitudinal movement. There are nine standard sizes which have design capacities from around 30kN to over 950kN. A range of stainless steel single dowel shear connectors is also available.
The dowel component is manufactured from 30mm diameter Duplex stainless steel, but is shorter than the ESDQ-L20 dowel. One end of the dowel is designed to fix into the stainless steel Ancon SKS24 Threaded Anchor cast into the face of the concrete, and the other end features a series of grooves to accept the Locking Plate. The sleeve component is the same as used in the ESDQ-L20.
The Ancon HLDQ, high load shear connector uses the same dowel component as the Ancon HLD, but the cylindrical sleeve is contained within a rectangular box section. This sleeve allows lateral movement or rotation in addition to longitudinal movement. The connector is available in seven sizes with design capacities from 24kN to over 500kN.
