Bar Gauge Heads VERITAS

Simply screwed onto 2 strips of 6 × 19 mm, measurements can be compared or transferred: for example, whether a glued drawer or a cabinet is truly square. If both diagonals are equal, the cabinet is square. By dispensing with numerical measurements, measurement errors are eliminated.

Included in the delivery are two brass pins to perform both internal and external measurements that are smaller than the wooden strips you are using. Wood is NOT included. You need to make the strips yourself!
