The self-locking split coupler (one touch coupler, fast coupler) is made of high-strength alloy steel. Its unique split screw sleeve and design of the jacking tightener make it suitable for connections in various working conditions, offering greater convenience and efficiency. Its tensile strength is over 1.10 times that of the base material, ensuring it is sturdy, durable, safe and reliable.

During installation, there’s no need to thread the end of the rebar — just insert the rebar into the coupler, and the connection is completed instantly. This eliminates the processing step of pre-stripping the thread head of rebar and the bulky auxiliary installation equipment, significantly improving construction efficiency, saving time, labor and costs.

Whether it’s housing construction, bridge and tunnel projects, nuclear power projects, or water conservancy projects, the self-locking split coupler (one touch coupler, fast coupler) can handle them all easily, meeting a variety of construction needs.

It is compatible with HRB400E and HRB500E rebars.

There is no restriction on the diameter of the rebar; the coupler is available in sizes 14, 16, 18, 20, 22, 25, 28, 32, 36, 40 and 50.
