Martinez Signature Series 2-in-1 Rapid Squares Limited Availability!

You’ve heard the rumors, and yes, they are true. We are adding back the level vial in our soon to be released Martinez Signature Series 2-in-1 Rapid Squares! We want every tradesman to feel good about their purchase and offer the function and quality you have come to expect from Martinez Tools.

Based on customer feedback, our new Aluminum Martinez Signature Series 2-in-1 Rapid Square, is derived from the original Martinez Titanium Rapid Square. The aluminum blade features a non-glare matte tumbled surface finish and has deep laser etched markings. The level vial has returned to the heel of the rapid square, and heels will now be offered in a choice of 5 different colors (Red, Black, Orange, Gold and Blue). The new heels are also available separately if you want to update your existing rapid square.
