Thoroughly pursuing the "tightening" function in all sizes! The handle is optimized to be longer for easier torque application.
The "CRB-DW4S" is a double wrench set from our original brand "Hi-5," which utilizes CFRTP with our unique molding technology, and is part of the tool series called "Cal Black." It weighs only one-third of that of steel, making it easy to carry. When connected to items like Styrofoam balls, it floats on water and does not rust since it is not made of steel. Additionally, we also offer the Cal Black monkey wrench "CRB-MW200." 【Features of CRB-DW4S】 ■ Non-slip matte finish even when oil is present ■ Can be set without a holder, allowing you to carry only the necessary sizes to the worksite ■ The handle is easy to grip and has a strong cross-section shape for flexibility ■ Adopts a hold type, making it suitable for secure tightening ■ Size markings are enlarged for improved visibility *For more details, please refer to the PDF document or feel free to contact us.
