Older porches and soffits often have a 3 in round box where a receptacle needs to go, and a rectangular cover won't seal on it. The Intermatic WP3103C is a single-gang, 2.75 in deep plastic in-use weatherproof cover that comes with a 3/0 adapter plate for 3 in round boxes. The clear lid mounts vertically or horizontally, and three inserts suit up to 16 device configurations.

Pro tip from the counter
Measure the round box before ordering. The adapter plate is made for a 3 in round box, and many exterior light boxes are 4 in round or octagon, which this plate won't seal to properly.
Best for: 3 in round exterior boxes, porch and soffit receptacle conversions, residential repair and service calls, homeowners' electricians on small jobs
