Versatile Straight & Zig-Zag in One Machine

The 20U-105C is designed to do much more than a simple straight stitch:

• Straight stitch & zig-zag in a single machine.
• Perfect for appliqué, satin stitch, decorative stitching, free-motion embroidery, and buttonholes.
• Three needle positions (left, center, right) make it ideal for zippers, cording, and topstitching.
• Knee-operated zig-zag width control allows you to taper or vary the zig-zag while sewing, great for appliqué and decorative work.

Industrial Speed with Servo Control

• High speed up to 2,500 stitches per minute (straight stitch) to boost productivity.
• Zig-zag sewing at up to 2,000 stitches per minute.
• Servo motor provides quieter operation, lower energy consumption, and excellent control at low speeds—perfect for precise work, corners, and curves.
