Dark Grey Cast Iron Roof Drain – RD-700

This dark grey cast iron roof drain Revit family features an elongated slotted dome strainer mounted over a circular outlet body. Rendered in coated dark grey cast iron, this assembly showcases a heavy-duty stadium-shaped dome strainer set atop an integrated clamping ring and circular sump bowl. The protective cage incorporates dense vertical perimeter slots alongside an open concentric circular top grate engineered to prevent debris ingress while permitting high-volume stormwater flow. Visible mechanical fastenings secure the slotted cage around the lower drainage body, transitioning downward into a central spigot pipe outlet designed for standard drainage piping integration.

The download is a 338 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 this component directly into a Revit MEP or architectural project to coordinate rainwater drainage runs across structural decks. Place the family at finished roof slab elevations, align connection points to vertical rainwater conductors, and route associated sanitary or storm pipework using standard routing preferences and slope calculations. The compact geometry ensures fast viewport regeneration without degrading project model performance.

Engineered for flat roofs, commercial parapets, and industrial deck build-ups, this heavy-duty fixture suits commercial warehouses, logistics facilities, multi-family residential developments, and retail centres. It integrates naturally into rainwater management details alongside membrane clamping assemblies, roof penetrations, and waterproofing build-ups.
