Features
- Rigid, well-designed
- The top of the beam is flattened so that when the trams are clamped in position, they will not turn from pressure on the points
- The 3" (75mm) points may be adjusted for length in the spring chucks and can be easily replaced with caliper legs or other attachments listed
- The ball points with 3" (75mm) holder permit working from holes up to 1-1/2" (38mm) in diameter
- A pair of 3" (75mm) caliper points is included with each trammel
- One tram has a fine-adjusting screw for the points
- Held in place by spring friction, which prevents them from sliding when the nuts are loosened for setting
- Each tram has a knurled swivel grip at the top that turns freely, making it very convenient to swing the tool when scribing circles
