Built for the sewing workroom
Set the pace. Guide the finish.
From T-shirt alterations and shirt construction to pillowcases and bedding, the 351G-241M provides a dedicated four-thread overlock setup for regular sewing and edge finishing.
Choose needle-up or needle-down
Select where the needles stop at the end of a sewing run. A consistent stopping position helps when repositioning your fabric between sections.
Adjustable differential feed
Fine-tune how the fabric feeds to help manage unwanted stretching or gathering. Test on a sample to find the right setting for your material.
Automatic lubrication
An automatic lubrication system with an oil filter supports the machine's moving parts. Keep the oil at the correct level and follow the operating instructions for routine care.
LED sewing-area light
Integrated lighting helps you see the fabric edge, needles and stitch formation clearly while setting up and sewing.
Adjustable stitch length
The stitch-length adjustment lets you set the spacing along the seam to suit the fabric and finish. Stitch length is separate from the width of the overlocked edge.
Complete industrial setup
Ready for your workroom.
Supplied built up with its table, motor and thread stand, on wheels for easier positioning. The table measures 1.2m long × 0.55m deep, with limited height adjustment.
A complete package for adding an industrial overlocker to your alteration shop, sewing room or garment-production setup.

Choose a sewing speed, needle size and thread suited to the fabric and seam assembly. Maximum speed is not a recommended setting for every application.
Is four-thread the right stitch for your job?
The 351G-241M is a four-thread overlocker, not a five-thread safety-stitch or coverstitch machine. For heavy materials, bulky seam intersections or a particular garment finish, ask us to check your application before choosing.
Keep your setup sewing well.
Choose suitable DC×27 / B27 overlocker needles and sewing thread such as Coats Astra 120, matched to your fabric and project.
View the official Singer 351G series brochure for manufacturer information. The brochure covers several configurations; this listing is the four-thread 241M model.
