Groz-Beckert 134 MR FFG. The Groz-Beckert MR needle style 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 in any direction. These needles are titanium-coated and will last much longer than standard nickel plated or chrome-plated needles thanks to its excellent abrasion-resistance. The MR needle style has maximum flexibility and bending to help reduce needle breaks and a deep scarf to mitigate skipped stitches.
