Needles for longarm machines (except A-1). Groz-Beckert #16 (MR 3.5).
Groz-Beckert 134 MR = 134 SAN 11 is specifically made for multi-directional use, which is exactly what longarm machines need. (Old packaging included 134 SAN 11, New packaging will not, but the needles are the same.)
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.
