Before you choose
Questions about SF-3803D-P
How does SF-3803D-P differ from SF-3802D?
SF-3803D-P is the three-needle version with a puller. SF-3802D is the two-needle chainstitch model. Choose the number of rows and the handling arrangement required by your seam.
Which needle spacing is available?
The selected model table does not establish one supplied gauge. Send the required spacing between stitch rows so it can be confirmed in the quotation.
What does the puller do?
The puller assists movement of the material after the sewing area. Its setup should be matched to the fabric and seam; the catalogue does not establish an output or anti-puckering guarantee.
Is it a three-needle coverstitch machine?
No. It is listed as a chainstitch machine. Send both sides of the desired seam so the stitch structure can be matched before ordering.
