Description
Introduction:   

Anchor coupler is used to elongate the anchor bar. It can be used in kinds of conditions which need different length of anchor bar. In the drilling process, anchor coupler enables direct end-to-end energy transmission between bars. Therefore it can reduce the loss of anchor bar.
 
Anchor coupler also can ensure the maximum percussive energy on the drill bit. According to the minimum load specifications, Sinorock anchor couplings can guarantee that the ultimate breaking load is the same as the self drilling anchor dimension.

Characteristic:

1. Being adjustable to kinds of anchor bars.
2. Couplers can elongate the anchor bars, so it is convenient to work in narrow space.
3. Easy connecting anchor bars to improve the work efficiency.
