Center Mark Magnetic Drywall Locator Tool

Great for first-time DIYs or the experienced handyperson, the Center Mark recessed lighting fixture locator uses powerful rare-earth magnets to help you accurately locate can-light fixtures for easy and accurate cutting of the holes in the sheetrock with no measuring required. The Center Mark can be used with traditional screw-in bulb cans to cut out 4", 5", and 6" recessed light fixture openings. This tool is not intended for recessed LED light fixtures. It eliminates costly measuring errors, keeps wasted drywall sheets out of landfills and improves your productivity.
No more lifting and lowering heavy drywall sheets multiple times. In three easy steps you'll be done: Just screw the Center Mark Targets into your recessed can light fixture, install the drywall, locate the target and cut the hole in the sheetrock.
