Kapro 325M 12 in. Magnetic Lock Zinc Head Combination Square innovates away the common locking nut with strong magnets that hold the ruler instead. It means that you don’t have to hold the precise measurement steady as you tighten the nut and, of course, don’t have to loosen it when you’re done. You simply push and pull the ruler through the square head’s magnetic field. The magnets create a strong resistance to movement so you can be confident that the ruler will stay where you set it. The magnets hold the sharp scribe in place if you choose to score the work instead of marking it.

Registering and transferring measurements from the board to blade/bit or board to board was never easier; the ruler is made of stainless steel and is permanently etched in inches and centimeters. The square provides 5 milled sides for superior accuracy and includes easy grip magnet-held stainless steel scribe, easy to read vial, and belt holster.
