Track type parallel ruler with counter balance

Drafting board with ratcheting stand








Function & Feature



A counterweight balances the blade and prevents it from falling.


High quality bearings of the parallel pulley system for the blade maintain precision indefinitely.


Waterproof drawing board will not deform.

A metric scale is attached on the left track.



An angle scale is attached on the right track.


Acrylic ruler on blade has beveled edges that prevent ink from spreading. Choose either the clear edge or the edge with a scale.


Replace paper by flipping the blade away.



The blade angle can be adjusted from 0 to +-15°.


The blade can float over the drawing surface between 1-3 mm.


The blade includes a brake system to lock position.
