Black Box FT2550A Manual page 6

Using the Level and Tool
1. Grip the tool by the vertical vial housing on side B.
2. Place the tool on the wall where the electrical box
is to be located.
3. Adjust the template until the horizontal vial
indicates the template tool is level.
4. For single-gang boxes, trace the template tool's
four outside edges on the right side of the box
(side A). For dual-gang boxes, trace the outside of
side A and side B. Some electrical boxes require a
square cutout (hole), so the corner material must
be removed.
