POWERSTITCH 2KU33 7" Top & Bottom Feed Heavy Duty Sewing Machine 

The POWERSTITCH 2KU33 is a portable semi-industrial heavy-duty single-needle lockstitch sewing machine featuring an independent top and bottom feed mechanism. Designed for demanding sewing applications, it is suitable for medium, heavy, and extra-heavy fabrics, including canvas, upholstery materials, and light leather.

This 7-inch throat space version offers a compact and practical setup that is easier to store while still providing excellent workspace for heavy-duty sewing. Its portable design makes it a versatile choice for workshops, small businesses, and users who require reliable walking-foot-style feeding without a large industrial machine setup.

Top & Bottom Feed System

The machine uses synchronized upper and lower feed dogs to move the material evenly in both forward and reverse directions. The lifting and feeding feet work alternately to hold the material securely, helping provide consistent feeding and even stitching when working with thicker fabrics and multiple layers.

Oiling & Maintenance
