The ATWH series is a professional low-profile hydraulic torque wrench offered by WREN. The pull handle together with the cassette acts directly on the nuts and with a narrow body the tool is well suited for tight spaces. ATWH covers 5 models with a key width of 19-175 mm. A flexible system where you change the cartridge to just the right size, cost-effective and efficient. WREN also offers reduction measures that simply give different key widths to the same cassette.
