Starrett EDP50270 Longer Trammel Points For 50A Series Trammels

Starrett 50CA (Longer) Points Only, EDP50270, are replacement trammel points designed for Starrett 50A series trammels. The two points extend the reach of the standard 50A setup, with lengths of 4-1/2" and 5" (113 mm and 125 mm) to accommodate larger radii and layouts. These points thread into existing Starrett 50A trammel heads and are sold as a points-only accessory, enabling you to swap in the longer contacts when your work requires extra reach without changing the rest of the trammel assembly. Compatible with Starrett 50A heads, the 50CA extension preserves the familiar screw-in point design and alignment, so you can maintain precise tracing and marking while expanding the tool’s geometry. Ideal for machinists and metalworkers performing large-diameter arcs, circles, or patterns where standard points fall short, these longer points help maximize the trammel’s effective span within the Starrett 50A family.
