Used for dividing and creating circles in hundreds of applications. I used them commercially insulating. They work on FSK and ASJ backed insulation. Also, on bear hair and sheet metal. I won't use them again, I'd rather see someone else get use out of them.

Lightly rusted and it has a washer riveted to the adjuster for extra leverage loosening and tightening.

1/2" - 16" radius

1" - 32" circles
