Engineered for concealed commercial installations, this water closet carrier Revit family features a cast iron fitting with four adjustable mounting studs. It features a heavy-duty dark grey cast iron drainage fitting combined with dual vertical structural steel support uprights. Centred on the assembly is an adjustable faceplate housing four extended white-coated mounting studs with hex nuts and washers to secure a wall-hung toilet bowl. The circular waste opening is protected with a black cylindrical threaded plug finished with a high-visibility yellow caution notice. Upper and lower bracket arms provide anchor points for floor and wall framing tie-ins alongside integral vertical waste and vent hubs.
The download is a 553 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.
Load the RFA file directly into your Revit MEP or architectural project to coordinate plumbing chases and wall cavity clearances. Align the vertical carrier legs within stud framing or masonry chase walls, connecting sanitary drainage and vent connectors to system pipework. The family assists clash detection against adjacent drywall studs, backing plates, and structural slabs while establishing correct fixture rough-in elevations.
Essential for commercial restrooms, healthcare facilities, schools, and corporate office washrooms, this in-wall carrier supports heavy-duty wall-hung toilets and commercial flushometer bowls. MEP engineers and BIM coordinators incorporate it during design development and construction documentation phases to resolve spatial conflicts behind toilet partitions. It pairs naturally with commercial sanitary fixtures, flush valves, and back-to-back plumbing chases specified in high-traffic public restroom layouts.
