re: Porter Cable 5" Random Orbit Sander

Very nice that you came over to the dark side. Lol glad you like it. I own De Walt 5" psa but have my eye on porter cables most aggressive 5" the 390

Well I do know that they make great tools and I do believe that the psa pad for the 332 will fit yours. Because its a standard for their sanders.
