For your outdoor lighting, Pro Lighting sells RAB Round Box Covers that are die cast and have one, three or four holes. Choose from regular or heavy duty covers. They have close up plugs which allow either slotted screwdrivers or Phillips head screwdrivers so installation is easier. The 1/8-inch thick weather seal gasket is made of a closed cell silicone rubber for seal that lasts a long time and which will not break or crumple up. Brass screws are included with the box covers.
