Expandable Trammel Points

Malco’s Expandable Trammel Points are offered in two sizes to handle a variety of layout applications. The TR42 expands to a large 42” (107 cm) radius and the compact TR18 expands to an 18” (46 cm) radius. The TR18 is compact enough to fit in most tool bags. Both sizes are made with all steel construction and nickel plated, corrosion resistant telescoping arms. A comfortable vinyl grip is also featured on both models. Points can be resharpened or replaced.


• Quick adjustability.
• Compact design.
