Overview

This simple accessory prevents your tape measure from slipping off the corner while measuring diagonals. The 90° inside corner securely straddles any outside corner, and rotates 360° to accomodate any rectangular object. It attaches easily to your tape with a single, powerful rare earth magnet. Use it while assembling drawers for a perfectly square batch. Also great for cases, frames and more. Slot for tape hook measures 1-1/8" wide. Made of durable plastic.

Thought this would be helpful and handy item to use when checking for square on large cabinets. However, loose fit makes it awkward to use. Would not buy again. Kind of a gimmick I didn't really need.

Kenneth B on Feb 28, 2018
It looks as though you need to subtract one inch from your measurement. Because in the picture it looks like the tool extends the tape measure out and extra inch for it to work. Is this true?
Mike T on Mar 24, 2018
BEST ANSWER: You would have to add to it, but I only use this to check square so as long as each cross measure is correct I'm happy. If you were using this tool to make cut based on calculations then I believe you would need to add the extra distance to your reading.

What a time saver!
I made two pair of double gates that each span about 9 feet. The magnet secured the tape measure hook end to the Square Check allowing me to easily measure at the opposite corner. Had no need for a second person (my lovely wife) to be interrupted just to make a quick square check. Of course it works just as well on smaller projects also.

Works Great!
This item does exactly what it says it does. Our only problem with it is that it is so small that we are likely to forget where it is when it comes time to need it. Because tape measures are inherently inaccurate, we use them more like a story board; remembering what our comparative measurements are. This devise makes such comparative measurements quite accurate and stable when measuring the distance between opposing corners.

Very Handy!
This thing is handy! Not for getting exact measurements of an angle because it offsets the tape slightly from the corner, but perfect for checking one dimension against the other!

Way to go to check Square.
This is by far the easiest way we have found to check square accurately especially over long lengths like we need for large door panels and windows. I only wish they would make one that could be used for the inside square measurements as well.

Very handy
I keep one of these in a drawer, magnetically attached to a 12-foot, Stanley rule. The combo is perfect for checking the squareness of box-like things like drawers and carcasses, and is superior to a helper that is not both personable and always available.

This is by far the easiest way to measure a box for square! If I lose or break mine, I'll definitely be buying another one.

Awesome and simple device! I use...
Awesome and simple device! I use it when measuring all my smaller projects to keep them square. The magnet holds the end of the tape in place. There is no problem with the square check staying on the corners on projects up up to 48". Very happy with my purchase. Should have purchased a few extra at this price.
