Description
Used to measure distance between two points or mark an arc or circle, these trammel heads fit a beam (you supply) up to 3/8" thick and 3/4" wide.
The die-cast heads have a black wrinkle finish. The hardened forged steel points have a threaded end for easy removal or replacement. One head has an adjustable point, allowing you to make precise adjustments easily without moving the clamps. The fixed point is 3" long; the adjustable point is 2 1/2" long. An included pencil socket can replace either point.
Made in USA.
