Precision Woodworking Squares. Experience perfect parallel marking with laser-accurate scales. Drawing lines parallel to the edge of your material is effortless with a Levoite precision T-Square in your workshop. The beam features a lip that rests on the top surface of your stock, preventing the tool from rolling like many T-squares. Precision machined scribing guides make it easy—just insert the point of a mechanical pencil and scribe a perfectly parallel line by holding the pencil in one hand and sliding the T-square with the other. Our product range includes Precision T-Squares, Framing Squares, Joiner's Saddle Layout Squares, Combination Squares, and Try Squares.
