Folding Parallel Rulers

Folding parallel rulers provide a fast, accurate method of drawing lines parallel to any reference line. Undercut and beveled blades are constructed from durable, clear plastic that will not warp or shrink. Corrosion-resistant anodized aluminum links allow smooth operation with up to 3” spacing. Anti-slip cork pads on back prevent slippage. Folding parallel rulers are available in 3 sizes.
