This vinyl siding mounting block kit adds a built-in electrical box for mounting an exterior light on 1/2-inch lap siding.

The block measures approximately 6.97 inches by 6.89 inches with a 1.46-inch depth, sized to fit neatly against your siding. Installation is straightforward: drill a hole through the siding lap, insert the included cable connector, mount the box with the included screws, then attach your light fixture.
