Choosing the Right Needles.

The Strongarm 2000U-33 uses standard industrial walking foot needles.
The needle types or systems are called "135x17" for fabric needles, and "135x16" for leather
needles. Quote those systems when you re-order needles.
Walking foot needles are available from Strongarm or from industrial sewing suppliers. They
are generally not available from domestic sewing suppliers.
Needles are sized in both Metric and "Singer" sizes. Singer sizes are more common in the
US, Metric in Britain and Australia.
The Strongarm sewing machine fits Singer size 12 to 23 needles which correspond to Metric
sizes 80 to 140.
