The ruler end of the ruler is equipped with a pull ring or ruler hook, brake type tape measure with a button device to control the tape winding. The ruler end of the depth measuring steel tape measure is equipped with brass ruler flower, which is connected with the ruler
The connection with the tape can be fixed, can also be hooked, the frame and the ruler should be the same number, the ruler according to its quality is divided into 0 . 7 female and 1 . 6 kg two kinds.
