1/8" and 1/4" Notches

The tool has 2 notches for devices that must be placed 1/8” or 1/4” from an edge (particularly a pocket). Simply align the tool so that the notch rests on the top of the pocket using the appropriate notch and place your device.

Grid Measurements

The grid at the top of the tool may be used for measurements up to 1/2”.

As shown in the diagram, the grid can be used to take measurements vertically and horizontally at the same time.

The adjacent diagram illustrates an example, where Device “B” is placed 1/2” up from the top of a pocket, and 1/2” to the left of Device “A”.

Box Measurements

The box at the bottom of the tool allows you to place devices using the rulers on both sides of the tool.

Use the center mark at the top of the box to ensure the device is centered within the cutout box.

Ruler Measurements

If a measurement is greater than 1 3/4”, the side of the devices functions as a ruler for taking measurements up to 3 3/8”.
