#21 FFG Point (Lt. ball) 134MR
Groz-Beckert 134 SAN 11 FFG (light ball point) size #21 (MR 5.0) x 10 needles. Groz-Beckert 134 SAN 11 (Special Application Needle, style 11) is specifically made for multi-directional use, which is exactly what longarm machines need.
Multi-directional design means more accurate stitching while moving the machine is any direction. Extra strength means maximum flexibilty and bending and a deep scarf prevents skipped stitches, less puckering, and less thread breakage.
