Better Office ProductsT Square, 18 inch Metal T Ruler, Carbon Steel, Double Sided Standard & Metric Laser Printed, Drafting - Architect - Set Square Companion Ruler, Black

Great tool for drawing

Excellent

This is perfect to use it with a steel cutter. The T shape of the ruler makes me so easy to cut a straight line for a large size of paper

I purchased this to line up my laser engraving materials. It is the perfect length for my 400mm x 400mm engraving space. Especially when I am using a jig.

Same problem as 12 inch model. The entire piece is one thickness which means there is no “catch” edge for the top T cross member to use against an edge of a desk, drafting board, cutting mat, etc. Otherwise beautifully done finish and graphics, but is not a traditional drafting type T-square.

This T-square is perfect. Solid black, with embossed white numbers. Metric on one side, imperial on the other. One piece of steel not two pieces joined at the T. This will be a great addition to my woodworking marking tools.

This may be "Carbon Steel" but it's exceptionally LOW carbon steel aka "Soft Steel."~ I picked it up with a short 3 foot long 2x4 laying across it and the T-Square actually bent. Now it has a permanent wave in it.~ One drop from workbench height and the thing would likely fold in half. Ok, maybe not quite that bad, but it would never be square again. It bends as if it's very thin and delicate aluminum or lead. It is ferrous however - magnets do stick to it.~ The scales are readable and seem accurate - just need to handle it with great care - which is not something one usually does with a "CARBON STEEL" tool like this.

Perfectly straight and angled to perfection.
