1- Inside thread is standard thread (right hand thread)

2- One side is left hand thread, another side is right hand thread.(positional rebar coupler )

3-The inside thread of two sides are different diameters(Reducer coupler)

Features and advantages

1- Easy operation, one machine can finish rib peeling and rolling process.

2- Save equipment and save labor, simple process , one operator use one machine.

3- Save cost and economical than lapping of rebar

4- Standard / positional /reducer coupler can be used in all kind of splicing construction site.

5- Shortens construction times.
