2 Pieces T Square Acrylic Ruler 23.6 Inches and 29.5 Inches Transparent Graduated T-Ruler Inch Metric T-Square Measuring Scale Ruler for Art Framing and Drafting

I love the top opened designed of these t-square the length l wanted. The sturdiness is a bit light in material. I feel like it can break if l’m not careful. It needs the acrylic material to be a bit heavier or stronger. The black print needs to be more black it’s a bit light.

The t part comes off for easy storage these are very sturdy and a good deal. The accuracy for is very functional and they are weighty enough to stay still while measuring yet not too heavy.

Purchased as precision drafting instruments...albeit modestly priced. After snuggly fitting the head to the straight edge, there was clearly a problem with both of these T-squares. The shorter one was off from 90 degrees by about 4 degrees. The longer one by about 2 degrees, rendering them both useless. I should have known better than to buy anything but a WESTCOTT pre-assembled T-square...

Great t squares for drafting! A lot of reviews noted inaccuracies and/or the bar being wobbly. This is an important part of the design design that makes it so you can tighten the screws where the bar meets the head so it is accurate and secure.

Each T-square comes in two pieces for shipping purposes. They interlock but rather poorly to maintain a tight 90 degree angle for "ever".

I'm please with this purchase, excellent quality at good price

Requires to be assembled, I expected this would just be installing 4 screws, but you have to slide a plastic piece into the t head. It is VERY tight, got one in the other snapped the plastic.

They've lasted many rough trunk rides without snapping in half like they feel they would, and I like that they're so portable.However, they should at least make the head steel, because these become NOT SQUARE very quickly...which is literally its one job.These come apart easily, and I noticed after re-assembling the first time that it's no longer a perfect square.There's a black piece of plastic which you screw onto the end of the clear ruler that slides into a slot on the top. Oddly, the screws don't even go all the way through both pieces, which would have fixed this issue. Designer needed more coffee.
