Adjustable TRAMMEL POINT

Adjustable trammels accurately measure and mark distances that are too great for conventional compasses and dividers. For layouts, marking templates, and drawing large circles. 6" off center eccentric points provide fine adjustment. Points can be replaced with pencils, ballpoint pens, crayons, or soapstone sticks, for marking various materials. Clamp onto beam 5/8" to 1-1/2" thick of any width or length.
