Parallel Rules and Straightedges


Ideal for measuring and drafting, straightedges are designed to be installed on a drafting table or drawing board and are used for drawing parallel lines. Parallel rules have straight edges joined by two arms that always remain parallel to each other, even when moved further away from each other. Both offer a range of calibrations for accurate measuring.


Blick also offers a variety of drawing boards with a straightedge or parallel straightedge. Lightweight and portable, many have a tilting mechanism for elevating the board to a comfortable angle, plus other convenience features such as a carrying handle.
