Review on 🚽 Oatey 43651 PVC Twist-N-Set Closet Flange, 4x4x4, White - Durable and Easy Installation for Your Bathroom Plumbing Needs by Predrag Hall

This flange has a special extra wide T-bolt slot. I've tried two different brands of T-bolts and both spin in the slot because they can't latch onto the sides of the slot. This means that you cannot tighten the toilet. Worse, if the nut corrodes, which they always do, the T-bolt will spin in the flange and you won't be able to remove the toilet in the future. Don't buy unless you have very wide T-bolts that fit properly in the slots.
