This hook works on Brother machines, single or multi-needle ones. It is meant to increase the embroidery area of the hat hoop.
I own 2 Brother Entrepreneur 6-Plus PR670-E.
It measures 1 inch in length. This Bypass Hook is the perfect mini tool to increase the embroidery area for your hats. This tricks your machine into thinking that it has a bigger embroidery area (without the usual measured limits). Give it a try in one easy step!
