スチール直角定規

I was laying out deck boards and this square made checking my 90s effortless—the 12x8 size covers multiple joists at once. The etched markings are deep and easy to read, which is a huge plus on a job site.

The etched markings are deep and easy to read, even on black steel, and it helped me square up a patio frame without any wobble. Fits comfortably in my hand, and the 90-degree angle was spot-on out of the box.

The 12-inch by 8-inch size is perfect for my workbench, and the black steel finish feels solid and durable. I’ve used it to check every joint on my new shelf project, and it’s been spot-on so far.
