Woodworking

I’ve burned through more rafter squares than I care to admit, but this Klein 9357SSQ has earned a permanent spot in my work van. After two years of daily abuse—getting tossed around, splattered with mastic, and dropped on concrete more times than I should admit—the double laser etching hasn’t faded one bit. That matters when you’re cutting ductwork transitions or laying out equipment pads and can’t afford sloppy measurements.

The 7-inch size hits the sweet spot for HVAC work. It’s compact enough to maneuver in tight mechanical rooms but still functional for larger layout jobs. The aluminum construction keeps it light without feeling flimsy, and the multi-functional markings actually get used, unlike some overcomplicated tools that just confuse the job.

Bottom line: it does what it’s supposed to do, every single time.
