OATEY 38550 Quadtro Plain Box, No Valves

No. The 38550 Quadtro is the plain box version, shipped with no valves installed. You get the high impact polystyrene box, the snap-on faceplate frame, and four support brackets for mounting. Valves are ordered separately, and Oatey offers them in both hammer arrester and no-hammer versions for this box.

Either. The 38550 body is built for top or bottom valve mounting, so you can run the supplies down from above or up from the floor depending on how the wall is piped. Since the box ships without valves, you pick the valve set and the orientation at install time.

Buy the plain 38550 when you want to choose the valve yourself, when you are standardizing on one valve type across a building, or when you are replacing a damaged box and reusing good valves. Go with a valved version if you want the whole assembly in one carton and the single lever, hammer arrester or standard, is already decided. Both use the same polystyrene body and 2 inch DWV drain connection.

It is Oatey model 38550, a white high impact polystyrene Quadtro outlet box supplied without valves. That is the number to quote for reorders when you are matching laundry rough-ins across units.

Yes, each box weighs about 1.55 pounds and occupies roughly 0.24 cubic feet, so a full pallet of laundry rough-ins for an apartment build moves easily. The polystyrene body takes the knocks of a framing site without denting like sheet metal.
