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 Industrial 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 EZ Set Stitch Length Plate helps to keep stitch length consistent when switching from forward to reverse. Switching directions 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, or take it in your boat or RV! The heavy-duty Industrial Carrying Case is a durable, reinforced carrying 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.

Included with the Industrial Carrying Case is our Elastic Protector Strap. This courtesy add-on helps to protect delicate fabrics and clear vinyl from snagging or scratching on the latches of the case. The strap snaps directly onto the case via pre-install snaps.

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. The Ultrafeed sews thinner assemblies, too, and can be easily adjusted to sew lighter weight home decor fabric so it can be your go-to machine for numerous projects. 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!

Gotta have one. Wait I have one:)) Need a portable one after mine was screwed to cabinet.


We've enjoyed this machine. Having bought the introduction version over 17 years ago. Added on the monsterwheel. Never use the monster. But checked it out. Also upgraded zipper/cord feet because I seem to sew zippers and cording a LOT. Not in the boat perse world. I was sold on this machine by one specific advertisement at the time. Will sew through all foam material without skipping. My ancient but beautiful 1915 commercial singer machine would skip if any foam or even vinyl fabrics with a spongy back to them was tried. It has lived up to it's reputation. Then along came the Zig Zag version. I'll kick myself for not upgrading right away when they sent me introduction prices too. Ahhh live and learn. I've repaired boat covers for friends. My only complaint is husband screwed down the foot peddle onto the custom made cabinet so it is no longer truly portable. So out of frustration as it does not have a detaching foot and power cord to the machine I am seriously thinking of buying that zig zag version now and making sure it never gets attached to a table period. (I could buy replacement cords then to make it truly portable again.) Right now we have three tents needing repairs including total custom zipper replaced. Being able to set it up outside on covered patio with lots of room...makes sense. I can't swing for the zig zag machine at this time. I worry now seeing a V-3 is coming out and these are closing out. But it'll be Dec before I can possibly pull money together due to some unexpected bills (New Well for one, gotta have water:))) I loved the stories of the soldiers by the way who used these machines in national guard and regular army etc. Wonderful machines and I recommend to most anyone. To the person who found the monster wheel too difficult to use. I wish someone had asked her/him to remove it and try it without via regular power. It really might have been all that was needed for success. I'm not a big person and I never feel the machine even with the monster is difficult to use. Just wish the cords detached at the machine itself. Checking to see what it would take to cut the orginals off short put on plugs and buy spare cords not available for this machine but similar are and then put outlet plugs on the old cut off part and new ones so I can just unplug and be portable again. Though I would love that Zig's a possible option. Get one before they are gone if you can swing it. If you sew or new to it. Brings out your creativity !!!!
