Ludwig - Precision Aluminum T-Square

Precision Aluminum T-Square

Draw perfectly perpendicular lines with a blade that won't bend or flex

Architectural drafting and technical illustration demand tools that maintain accuracy through thousands of measurements and countless edge-guided cuts. Ludwig Precision T-Squares deliver exactly that reliability. Hard-tempered aluminum blades resist warping and flexing under pressure, while secure riveting, four rivets on standard models, five on heavy-duty versions, eliminates the wobble that ruins precise work.

The calibration system addresses real drafting needs: 32nds measurements through the first six inches on top handle fine increments, while centimeter and millimeter markings along the bottom accommodate metric work. Standard models feature 12-inch plastic heads calibrated four inches on each side of the blade; heavy-duty versions upgrade to extra-wide 14-inch heads calibrated five inches out. This dual measurement system means you're covered whether working from imperial or metric references.

High-impact black plastic heads withstand the inevitable knocks and drops of active studio work. The super-rugged construction maintains alignment session after session, while extruded aluminum construction keeps the tool light enough for comfortable positioning yet substantial enough to guide blades without shifting. Drafters working on large format boards and illustrators laying out complex compositions both appreciate tools engineered for precision that lasts.
