The Sailrite Ultrafeed LSZ-1 PREMIUM Sewing Machine package features our powerful, portable, straight stitch/zigzag walking foot sewing machine loaded up with all of our best accessories. This package is perfect for someone who needs an easily portable, heavy-duty machine, for boat owners looking to sew heavy canvas or sails, or for the sewer who wants all the bells and whistles. The Ultrafeed LSZ-1 Premium Package features the Ultrafeed LSZ-1 Sewing Machine (Patent #6499415) in the Deluxe Carrying Case and all these great accessories:

  • Monster II Balance Wheel
  • 1” Swing Away Binder
  • EZ Set Stitch Length Plate
  • Integrated Thread Stand
  • Flex20 Light
  • Deluxe Magnetic Sewing Guide
  • Kickstand
  • Left Roping Zipper Foot
  • Cording Foot Set for Large Welting
  • Needle Assortment Pack

The Ultrafeed LSZ-1 Sewing Machine excels in performance and versatility, sewing in both straight and zigzag stitches. Built with the toughest, most reliable parts, the Ultrafeed is designed to make sewing through heavy materials like sailcloth, heavy canvas, denim, and upholstery fabrics easy (tried and true in up to 10 layers of heavy canvas and 8 layers of Dacron sailcloth).

Double the Power

With the Ultrafeed Premium Package you not only get the standard Power Plus Balance Wheel, but also the extra large, extra powerful Monster II Balance Wheel. The Monster II is a solid 7 lb. nickel-plated steel balance wheel with twice the size and power of a traditional balance wheel. It also comes with a hand crank and creates enough momentum to sew even heavy fabrics without electricity. Powering the machine is a 110 VAC motor (6600 rpm at 1.5 amps) and a cogged belt and pulley drive system. Operate using the fully grounded, variable speed, electronic foot control.

Patented Posi-Pin

Sailrite’s patented Posi-Pin (#7438009) Clutching System provides 100% power transfer from the balance wheel to the needle. This unique system keeps the clutch from slipping while sewing heavy, hard to penetrate fabrics.

Simple, Straight Forward Sewing

An extra wide (19mm) zigzag mechanical walking presser foot works with the feed dog to pull thick layers of fabric through the machine at consistent speeds for symmetrical stitching. The latest improvement to the Ultrafeed, the new EZ Set Stitch Length Plate, helps to keep stitch length consistent when switching from forward to reverse. Switching from forward to reverse is made quick and easy by the spring loaded stitch length lever.

The presser foot features a built-in welting tunnel for sewing piping and a needle positioning lever moves the needle left, right and center so you can sew marine zippers without changing the foot. For those times when you need the needle even closer to what you are sewing or you need to sew extra large piping, this package includes a left roping zipper foot and a large cording foot.

Conveniently Portable

The Ultrafeed is built to be tough enough to go wherever you go. Move it around your home, take it on your boat, or in your RV! The heavy-duty Deluxe Carrying Case is an instrument quality case that protects your machine so you can sew and store it anywhere. The Integrated Thread Stand attaches directly to the case’s base and swivels for convenient use and quick storage.

Sewing Capabilities

The Ultrafeed features a 3/8” high foot lift and a best-in-class needle bar stroke, so you can sew virtually anything you can squeeze underneath the foot. Set the variable stitch length up to 6 mm in straight stitch and up to 5 mm in zigzag width and you’re ready to go. The Ultrafeed will easily sew through fabrics like:

  • Heavy canvas
  • Sailcloth
  • Upholstery fabrics
  • Denim
  • Vinyl
  • Window material
  • Soft leather
  • Drapery material
  • And more!
