Self Centering Tape Measure
By Lufkin (L625SCTMP)
Using the Lufkin® Self-Centering 25' tape is amazingly simple. To find the center of the object you're measuring, you just measure it, reading from the top row of black numbers. Then, you look directly opposite the black numbers to a row of red numbers to see the center measurement. Measure to that number and you've marked the center point of your work piece...it's that easy!
