Maxi-Lock Serger 50wt Polyester Thread – White | 3000yd

Maxi-Lock is American & Efird's all-purpose serger thread: 100% spun polyester, 50wt (Tex 27), 3,000 yards per cone. It feeds evenly at overlock speed, recovers after seams stretch, and resists shrinking, abrasion and mildew — for seam finishing, garments, linings and rolled hems.

Most sergers take three or four cones, one per thread position.
