The K09-SYNCRO is a lighter, more ergonomic, and simplified mechanical crimper that provides a solution to eliminate misalignment of dies. The unique SYNCRO die design features one-handed die change rotating both dies simultaneously. The laser-cut dies are marked with the AWG die sizes and the die selection wheel is color-coded for easy identification. The single color-coded die selection wheel increases user efficiency by aligning the die with the correct lug size. The dies are built into the tool to eliminate loose pieces, speeding up the crimping process. In addition, the dies are life tested beyond 10,000 crimp cycles and are phosphated, polished, and tempered for increased durability and corrosion resistance. Engineered with an engraved crimp groove, the die index number is inscribed on the crimped lug for easy verification the connection was made properly. The new locking, extendable handles have four length positions providing increased maneuverability and leverage. The ergonomically designed handles and molded grips make the tool more comfortable which can result in up to 35% less muscle effort than the competition.
