Starrett C251C Steel Beam Trammel, 18" Maximum Dividing Range, 36" Maximum Circle Scribing Diameter Range, 20" Beam Size

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
