Merrow Catalogue and specifications
Merrow MB-4DFO-2.1 catalogue (PDF)
Merrow's sheet for the MB-4DFO, the industrial flat overlock machine that sews Merrow's ActiveSeam, a flat seam made as an alternative to flatlock, interlock and overlock. The seam lies flat against the skin, so base-layer, activewear and sports apparel makers use it on lightweight knits.

What the Merrow MB-4DFO-2.1 catalogue covers
One page in English with the MB-4DFO and its specifications. Merrow shows three stitch variations from its curved needles: two needles with three threads, and one needle with two threads at two widths.
Merrow hand-builds each machine in the USA, so allow for the build time when you plan. Al Borj supplies, installs and services the MB-4DFO-2.1 from Sharjah and Accra.
Machine type: Flat overlock machine (ActiveSeam).
