The Faithfull Depth Gauge and Protractor is a dual-function measuring tool designed for accurate angle and depth measurement in a single operation. This versatile gauge features deep etched graduations marked from 0 to 180 degrees in opposite directions, allowing tradespeople to read both direct and supplementary angles without additional calculations. The tool combines a protractor head with a graduated rule blade extending to 150mm (6 inches), marked in both metric and imperial dimensions for versatile measurement applications. The dual graduation system displays measurements in 0.5mm increments and 64ths of an inch, making it suitable for precision work across different measurement standards. Ideal for carpentry, joinery and general construction tasks, this depth gauge proves particularly useful when setting angles for cuts, checking joint depths, or measuring recessed features. The knurled thumb nut provides secure blade locking at any chosen angle, ensuring consistent repeated mea
