So I got it a few weeks ago but just installed it yesterday. Everything went smoothly and there is a lot of space inside the cover. This part was especially important to me as it is the cover of the recipe. that feeds my septic tank pump. So there's a cord that plugs into the outlet and it's designed for the float in the tank, and the pump itself connects to that plug from the back. So when everything is connected you need a lot of space under the lid and this one has it. Smaller ones have too little space and the lid is weatherproof. Just not this one! Perfect and thank you.
