About Rebar Couplers

Rebar couplers connect adjacent rebar while simplifying the design of reinforced concrete.

Couplers interact with the reinforcement bars that they connect by modifying their physical dimensions. Couplers apply end treatments to connected rebar according to the connection needs of the coupler. Bar geometry shortens to accommodate the connection with the coupler.

Coupler families have customizable geometry. You can create and modify nearly any type of coupler with separate representations in 2D and 3D views. Type parameters define dimensions, the sizes of bars to which the coupler connects, and the end treatments that are applied to the rebar.

The coupler geometry is automatically rotated to show in the same way in 2D views, when the option Align to View is checked.

In 3D views, the coupler geometry is always aligned to the bar end. When rotating the coupler, this is the default position.

Example showing couplers aligned to the end of bars in a free form rebar set.

To create complex geometry and display it in a realistic way in 2D views, you can edit the coupler family and uncheck the Align to View option.
