Levoite™ 6/12 INCH Precision Aluminum T-Square Ruler

They work for my purposes. The accuracy seems pretty good.

Great quality and fair price. Excellent T square and should last a lifetime. You get what you pay for especially in this case. I build furniture and I have a very nice wood shop with other T squares but this is top of the line.

It's also very accurate. I compared it to a similar styled ruler that's very popular for some reason and this 6" gauge is not only just as accurate but it accepts fine point SHARPIES!!! I couldn't imagine a fabrication scenario where you wouldn't prefer the use of a 0.5' ink marker versus a 0.4" lead pencil. My fabrication skills may not be the best, but as far as plotting an accurate pattern with true 90deg angles, this little ruler did not disappoint. You can also see I ended up ordering the 12" version of this ruler in my picture, because it works.

Absolutely excellent t quality and precision
