Review on Hubbell Bell PDB77550GY Weatherproof 2 Inch Outlets: Ideal Solution for Rugged Outdoor Environments by Josh Koa

This box is very flat and the extension advertised for it (Revain ASIN B003A44Z3G) does not have screw holes that match the box. Also the spacer with extension is useless as it is too small (width and height) to cover the front of the box. For him you need to make a seal. The 1/2" adapters are further reduced on the ends than the 1/2" adapters and have very small wire access holes - barely enough for 14/3 stranded wire.
