Comfortable grip, double TPR handle, ergonomic design. When the nylon clip is fully open, the maximum opening is 3.7-Inch, which allows it to hold thicker material.

The wide rotary jaw can be adjusted automatically to adapt to the uneven surface, so that it has good matching and stable grip, and can also protect the working surface.
