The M1 Series Protape features a unique fold-down ‘Scribe’ which allows you to measure and mark in one step, as well as built-in measuring guides at the edges of the blade that help you to see precisely what your measurement is. The nylon coated blade of the tape has Fractional Read on the front and Vertical Read Carpenter’s on the back. The body of the tape is encased in a protective and comfortable rubber with an extra large, double edged endhook and a durable push button lock.
