Grey Cast Iron Promenade Roof Drain – RD-300-CP15

A heavy-duty promenade roof drain Revit family featuring a square slotted grate top and a perforated stainless steel extension collar. The assembly comprises a square slotted cast metal grate set into a rigid perimeter frame, designed flush for pedestrian promenade deck surfaces. Beneath the upper grate, a cylindrical perforated stainless steel riser collar prevents debris infiltration while maintaining lateral drainage. Threaded vertical adjustment rods secure the upper deck flange to the lower clamping ring and heavy-duty cast iron sump bowl. Coated in a uniform grey industrial protective finish, the unit features cast perimeter tabs, bolt-down hardware, and a bottom circular spigot connection intended for vertical stormwater discharge piping.

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.

In Autodesk Revit, load this RFA component into MEP or architectural models as a plumbing fixture. Position the drain along structural roof slabs, decks, or terraces, aligning the upper grate flush with finished pavers or ballast surfaces. MEP engineers can connect the bottom discharge pipe connector directly to gravity storm drainage pipework, configuring system types, slope requirements, and drainage flow parameters to coordinate slab penetrations.

Engineered for commercial, institutional, and high-density residential facilities, this promenade deck drain is suited for flat roof terraces, rooftop amenity spaces, green roofs, and elevated plaza decks. It integrates effectively into ballast paving assemblies, inverted roof membrane systems, and exterior pedestrian walkways.
