Grey Cast Iron Parapet Scupper Roof Drain – RD-290

This industrial parapet scupper roof drain Revit family features a heavy-duty angled cast iron body with slotted vertical and horizontal grates. Engineered for perimeter stormwater collection, the assembly combines a horizontal deck flange with an upright parapet faceplate at a ninety-degree angle. Both faces incorporate dense vertical drainage slots secured with mechanical hex fasteners to prevent debris ingress while maintaining rapid runoff flow. The rear junction tapers into an angled cylindrical hub connection designed for secondary spigot or clamp plumbing joints. Coated in a dark grey protective enamel, the cast metal surface displays subtle textured tooling marks and recessed hardware pockets suited for flush parapet wall transitions.

The download is a 317 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.

Within Revit MEP and architectural templates, load this RFA component into gravity drainage or roof plumbing systems. Position the drain along exterior parapet upstands or roof edges, aligning the horizontal flange with roofing membranes. Connect sanitary or stormwater pipework directly to the rear outlet fitting to verify slope tolerances and avoid clashes with structural perimeter beams or wall reinforcement in BIM coordination models.

Primary applications span flat roof commercial buildings, logistics warehouses, parking decks, multi-family residential terraces, and industrial facilities requiring secondary overflow or perimeter drainage. The unit coordinates smoothly with perimeter flashing, waterproofing membranes, and internal storm downpipes. Specifiers and MEP engineers typically search for this component under scupper drain, parapet overflow fitting, exterior roof drainage box, or commercial gravity drain detailing.
