Item Description

The Sailrite Ultrafeed LS-1 PLUS Sewing Machine package features our powerful, portable, straight stitch walking foot sewing machine with some of our favorite accessories. This package is perfect for someone who needs an easily portable, heavy-duty machine or for home sewers looking for a sewing machine that can handle heavier materials. The Ultrafeed LS-1 Plus Package features the Ultrafeed LS-1 Sewing Machine in the Deluxe Carrying Case, with the Integrated Thread Stand and the Flex20 LED Light.

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

Double the Power

Included with the Ultrafeed is the Power Plus Balance Wheel, which has twice the power and size of a traditional flywheel for more slow speed power and control. Turning that wheel and powering the machine is a 110 VAC motor (10,400 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

A mechanical walking presser foot works with the feed dog to pull thick layers of fabric through the machine at consistent speeds for symmetrical stitching, in both forward and reverse. The presser foot features a built-in welting tunnel for sewing piping and the needle is offset to the right in the presser foot, so you can sew zippers without changing the foot.

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.

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 and you’re ready to go. The Ultrafeed will easily sew through fabrics like:

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