Square One Tape Measure, 25'
Make sure you’re square with the FastCap Square One Tape Measure. This 25'-long tape measure has all the conveniences you’ve come to expect from FastCap – ergonomic rubber casing, erasable notepad...
The Square One Tape measure has two scales on the 1"-wide high contrast blade. The top of the blade is a traditional imperial scale. The bottom has a special hypotenuse scale that displays the length of the hypotenuse for that measurement.
Most people who have taken geometry are aware that a2+b2=c2 when measuring the sides and hypotenuse of a 90° triangle. Now, you don’t need to remember the formula. Simply take the measurement of the first side of your square and copy it over to the second side. Using the Square One Tape Measure, make a triangle with the blade as the hypotenuse between the end of the first side and your mark. The hypotenuse scale of the tape should show you the same distance you originally measured. If the number on hypotenuse scale matches the length of the legs, you know you are in square.
For example, if you’re first side is 12", measure the second side to 12" and mark it. Then run the tape measure from the end of the first 12" side to your mark 12" from the corner, and you’re hypotenuse scale should show 12".
You can check the square on all four corners of deck, floor, table, concrete pad and more. Measuring the whole short side will let you see the drift off of square, while measuring a small section of each leg will let you check the square of the corner.
