Introducing Thread Ruler
The first commercial
product of its kind that can draw elliptic figures.
Draw Ellipse, Arcs, Circles, Angles and Parallel lines
A combination of a protractor, compass and ruler as a geometry
set with a unique thread construction that enables the user to draw elliptic figures.
Thread Ruler is a patented product (Patent #7080459) for its capability of drawing
an ellipse, arcs, circles, angles and parallel lines.
A Complete Geometry Set in One piece.
The
single piece Thread Ruler replaces a multi-part traditional geometry set (that usually
comes with seven or eight discrete pieces) at a much lower cost. As an introductory product
we have reduced the pricing on the product to $1.45/pc for a quantity of 1000.
