Top Features

Overlock Precision
The built-in seam guide takes the guess work out of seam allowances. Use the conveniently located gauge on the guard cover. This will give you accurate seam allowances while your overlocking
Multi-Purpose Foot
The multi-purpose foot allows overlocking and the addition of tape, elastic, ribbon, or sequins, while snap-on presser feet make it easy to switch to specialty feet for expanded creative options.
Easy Built-In Roll Hem
Achieve a beautiful roll hem edge very easily by moving the lever on the needle plate towards you and adjusting one of the tension dials.
Differential Feed
Differential feed is to ensure that you always have a perfect seam. The differential feed also gives you the capability to gather lightweight fabrics and give you a lettuce leaf edge on different texture fabrics using the rolled hem facility.
