OATEY 43500 3 in. or 4 in. ABS Offset Closet Flange with Metal Ring without Test Cap

That is what the offset is for. The 43500 offset closet flange gives 1.42 inches of offset between the pipe connection and the bolt ring, so a rough-in stub that landed too close to or too far from the wall can still be brought under the toilet. On top of that, the metal ring rotates, so you can spin the closet bolts into the right alignment after the flange is solvent welded. Between the 1.42 inch offset and the rotating ring, most out-of-position stubs get corrected without cutting the floor open and re-piping.

Use a straight flange when the drain stub is where the toilet wants it. Reach for the offset, like the 43500 with its 1.42 inch offset, when the rough-in missed: the stub is too tight to the wall for the fixture rough-in, or slightly off the centerline of the closet. Offsetting the flange is far cheaper than opening the floor and moving the pipe. One caution: the offset shifts the opening off the pipe axis, so it reduces clear flow area compared to a straight flange, and it needs to be oriented before cementing so the ring lands where you actually need it.

Six screw holes around the ring secure the flange to the subfloor, so you get six anchor points rather than the four common on lighter flanges. Fasteners are not part of the flange, so pick screws suited to what you are anchoring into, wood subfloor or concrete. On an offset flange the extra anchor points matter more than usual, because the load from the toilet is not centered over the pipe.

No test cap. The 43500 is the version without one, so it will not hold water for a DWV pressure or standpipe test on its own. If the rough-in still has to be tested, either test before setting the flange or order the offset flange version that includes a test cap. Once you are past testing and setting finished floor, the no-cap version is the straightforward choice.

You get the ABS flange body with the rotating metal ring. Closet bolts, floor screws, wax ring or waxless seal, and ABS solvent cement are all separate. Plan on all four before the toilet goes down, since the flange only provides the anchor ring and the pipe connection.

Metal, on an ABS body. The metal ring is what carries the closet bolt load, which is the usual failure point on all-plastic flanges when a toilet rocks. It also rotates on the body so the bolt slots can be indexed to the fixture rather than the pipe. The flange itself is black ABS.

Order it as Oatey 43500, an ABS offset closet flange with metal ring and no test cap. It weighs 0.9 lb apiece, which is useful when a property maintenance crew is stocking a truck or building a multi-unit turn kit.
