When you want to make the most of your serging time, with professional results, the MyLock 634D is unmatched. It has 2 needles and 2, 3 or 4 thread overlock stitching. Threading is a breeze due to color-coded thread guides and an easy lower looper threading system.  The MyLock 634D also lets you quickly switch to rolled hemming without changing the needle plate.

Designed for sewists who want dependable performance and beautifully finished seams, this powerful serger offers 2-needle capability and flexible 2, 3, or 4-thread overlock stitching options to suit a wide range of projects.

Switching to rolled hemming is fast and convenient—no need to change the needle plate. Whether you’re finishing garment seams, creating durable overlock edges, or adding decorative rolled hems, the MyLock 634D provides smooth, consistent stitching every time.
