    • Works great
Great tool. I need more of them.

    • Love this combination square.
I like the magnetic scale that can be easily removed. Great combination square does what I need.

    • Much easier to use than the old style
I’ve had cheap ones and expensive ones, both can be a pain when putting the scale (some might call that the “ruler”) back into the square casting. This magnetic version gets rid of that issue. The magnets are plenty strong, I have had no negative issues with the scale coming out during use. As the description notes, this square is specially designed for use by electricians but it can be used for any work, in my case the the one side of the scale is superfluous but the other side marked in inches 1/8” & 1/16”. I would imagine that they make one without the other markings but this works for me. It would just be a little more convenient if both sides were in inches or even one side metric. ... show more

Been in the construction industry for 37 years. I can say this is a decent tool. I would buy again. Easy to read numbers. Sturdy build.

    • Easier to use and holds dim well.
Wasn’t sure of the magnets holding strong enough but so far they do a very good job. Not as secure as being lt but if you use it correctly it holds very well.

    • Square
Commercial/industrial electrician I’m not a huge fan of Klein anymore and to many other brands does everything better for less money. But this is different. It’s a phenomenal layout tool and the flat bar is removable as it’s only help on by a magnet. This is better than my flat layout tools unless the box or panel is already mounted to a wall. Definitely worth the money. ... show more

    • Amazing tool
This tool is amazing! Worth every penny, it has all the different spacings for laying out electrical panels and keeps everything square and all measurements accurate. The engravings on the ruler side make it clear and eligible even after harsh use

    • Well-engineered precision product
This is a well-engineered item and the square is actually, well, square -- an important attribute in a square. I mention this because other products fail in this regard. The magnetic attachment takes a bit of getting used to, though. The ruler is a bit reluctant to slide because of the magnetic "stickiness". After you've used it a few times, this becomes a non-issue. A quality product and good value for money. ... show more
