These handy double squares are indispensable for setting up machinery and for performing a host of shop layout tasks.

They are manufactured in accordance with EEC Class 1 accuracy standards and are guaranteed to be square to within 0.0015 (one and a half thousandths of an inch) over the length of each blade. 

They have hardened and tempered no-glare satin chrome stainless steel blades. Blade marking are precision photo etched and then black filled for easy readability. Blades have quick reading  graduation markings with 1/8th and 1/16th on both sides.  Traditionally, the most common graduation markings used by woodworkers are 4R, or 1/8ths and 1/16ths on one side and 1/32nds and 1/64ths on the reverse. The fact is most woodworkers never use the finer 1/32nd and 1/64th markings as they are hard to read, too precise for most tasks, and just plain confusing, e.g., just what does 51/64th or 19/32nds really mean? So, we had these squares made with the most commonly used 1/8th and 1/16th graduation marks on both sides.  

Square heads are cast and then precision machined. Square head color is Square heads lock down tight via locking knob.

Squares come in a cardboard box.

Available in with either a 4” or 6” blade.
