About this asset

Crafted for plumbing and drainage layouts, this dome grating floor trap Revit family features a slotted hemispherical strainer on a circular base ring. The component comprises an open slotted hemispherical dome seated on a flat, circular mounting flange. Radiating vertical ribs taper upwards toward a central solid cap, creating regular apertures designed to allow liquid flow while catching coarse debris. The reflective silver metallic surface depicts cast or stamped metal construction, such as stainless steel or chrome-plated brass. Proportioned for standard circular drainage openings, the profile maintains consistent rib spacing and a clean perimeter lip designed to sit flush against surrounding slab or floor finishes.

The download is a 410 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.

Designed for MEP and architectural modelling in Revit, this RFA family can be loaded directly into project templates or MEP coordination models. Place the component directly onto floor surfaces, roofs, or connect it to vertical drainage risers. Material parameters can be adjusted via object styles to match required cast iron, bronze, or brushed stainless steel specifications, ensuring accurate graphic output in floor plans, sections, and BIM schedules.

Engineered for rainwater collection and facility drainage, this dome grating floor trap suits commercial flat roofs, open terraces, plant rooms, exterior balconies, and utility basements. Designers and public health engineers specify dome strainers to prevent gravel and foliage from obstructing rainwater pipes and gravity drainage stacks. The asset fits seamlessly alongside rainwater downpipes, waterproofing membranes, and stormwater pipework within residential towers, industrial warehouses, and institutional healthcare facilities.
