Description
Description
The JACK 20719007 Overlock Upper Knife is a genuine OEM replacement part for JACK E4S, C5, C6, and C7 series industrial overlock sewing machines. The upper knife works against the lower knife to trim fabric edges cleanly during overlocking. A worn or dull upper knife produces ragged edges and uneven trimming — this replacement restores sharp, consistent cutting performance to factory standard. Sold as 1 piece.
