Flashing for an Outdoor Light Fixture Box

I've discovered some plastic flashing blocks that work great for protecting outdoor electrical boxes from getting water inside them.  It's a two-piece unit... once piece goes over top the electrical box before the siding goes on... and the second piece goes on after the siding is installed.

This is the electrical box for the outside light at the front door.


Here's the back half of the flashing block.  It just slips over top the protruding edge of the electrical box.


Now the siding goes on.


Now the front half of the flashing block slips on overtop and outside of the back half.


Once the light fixture is installed, the electrical box is well protected from getting wet inside.
