Bought this to install on my Aluminum enclosed snowmobile trailer. I installed it on the left front of the V nose because that is where the Diamond plate was. Located there because the screws would have more purchase power.Two inch hole saw did the trick . Had to go thru the outer skin ,then the inner wood. Because the outlet pigtail is offset I had to cut a 1/2 inch Notch so the whole receptacle would slot right in.Finished the job with plastic wood to seal off the inside circumference .The receptacle is well built and am especially pleased with the quality of the rubber cap . Looks like it will seal out salt quite well and we shall see about the durability and corrosion resistance of the metal blades .Some of these receptacles come with two pigtails and that's good but I just use a three way adapter and good to go there .Hope this helps.
