With some three decades in R&D and fabrication of hand tools, Chang Loon aggressively develops and offers innovative, patented items to meet changing market demands in addition to offering professional-grade ratchet wrenches and bolt cutters.
Promoted globally under ProRatchet® and High Tensile brand, the aforementioned are well designed to feature higher user-friendliness, safety and labor-efficiency than conventional models. We also offer wide-ranging product lines, including professional-grade ratchet wrenches, 3-in-1 cutters and aluminum-alloy bolt cutters that are patented in Taiwan, Southeast Asia, the U.S., and Europe.
