The Jack E5 Thickness-Adjustable Direct-Drive Overlock Sewing Machine is a high-speed, heavy-duty industrial overlock machine engineered to handle a wide range of fabric weights.

Built with an integrated direct-drive motor, an upgraded long-stroke needle mechanism, and an ultra-wide operating voltage tolerance (90V–295V), the Jack E5 delivers up to 5,500 S.P.M. with zero skipped stitches or thread breakage—even over thick cross-seams and heavy denim.
