Alright, if you're installing a toilet, this Oatey closet flange is exactly what you need. It's designed to connect your toilet to the plumbing system and sits nice and flush with the floor. The stainless steel ring is corrosion-resistant and has this clever bolt slot shelf that keeps the bolts from falling through during installation - such a lifesaver! It fits inside 4-inch PVC pipe or over 3-inch Schedule 40 DWV pipe, giving you some flexibility. There are 8 screw holes so you can position everything just right, and you can even rotate it to align the bolts perfectly. The kit comes with all the bolts, nuts, washers and gaskets you need. Oatey has been making plumbing stuff for over 100 years, so you know it's good quality. Whether you're a pro plumber or a DIYer tackling a bathroom renovation, this flange makes toilet installation way less frustrating. The stainless steel means it won't rust out on you, and that bolt shelf feature alone is worth it - no more fishing around for dropped bolts in awkward places!
