With Spot Finder in Spot Guard Gles, you can use a simple and quick magnetic search to find the right place for drilling when the roof is in place. Twist up and gather the wiring so it doesn't get pinched between plaster and Spot Guard Gles, or get caught in the drill. The kit contains 6 Spot Finders for placement in the Spot Guard Gles, as well as 1 targeting magnet. Spot Guard Gles is updated with 5 brackets for alternative placements where the Spot Finder is simply pushed up and screwed in completely without tools.
