Calculated Industries 8110

The Calculated Industries 8110 is a drywall cutout tool that helps you make perfect cutouts for recessed lighting fixtures. It can be used for 4", 5", and 6" recessed lighting fixtures.

The 8110 is easy to use. First, screw the Center Mark Target into the light bulb socket inside the recessed light fixture. The magnet should extend below ceiling level.

Then, cover the recessed light fixture with drywall. The Center Mark Target will automatically adjust upward so that the magnet rests directly on the ceiling surface in the center of the light fixture.

Next, pass the Center Mark Locator across the area where the Target is located. The Locator will snap into place when it finds the Target.
