XLCT series is a professional-grade hollow hydraulic torque wrench. Compared with the drive type hydraulic torque wrench, the hollow hydraulic torque wrench acts directly on the nut, and its volume is thin and light, which is very suitable for working in a small space. The XLCT series hollow wrench can adapt to different working conditions by replacing the working head and assembling the reducer sleeve. It covers all bolts from S19 to S175.
