Needles for longarm machines (except A-1). Groz-Beckert 134 SAN 11 (Special Application Needle, style 11) is specifically made for multi-directional use, which is exactly what longarm machines need.
Titanium-coated needles last longer and run cooler.
Multi-directional design means more accurate stitching while moving the machine is any direction.
Extra strength means maximum flexibilty and bending.
Deep scarf prevents skipped stitches, less puckering, and less thread breakage.
