About this asset

This perpendicular register boot is a Revit family fitting designed for transitioning between rectangular and round ductwork runs. This perpendicular register boot serves as a specialized transition fitting for HVAC distribution systems. It features a rectangular connection interface on the primary face and a perpendicular circular spigot for branch ducting. The geometry is clean and functional, intended for precise integration into standard mechanical layouts. Key parameters for width, height, and radius are clearly defined to ensure accurate sizing within the Revit environment. Constructed as a standard mechanical fitting, the component maintains clear connection points to facilitate routing and system connectivity across diverse building services projects in both commercial and residential sectors.

The download is a 256 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.

Engineers can insert this family directly into a Revit mechanical project by dragging it into a duct run or placing it at the terminus of a branch. It is designed to host onto existing rectangular ductwork, automatically snapping to the specified connection points. Users should adjust the instance parameters to match the nominal duct dimensions and ensure the circular connection aligns with the required branch diameter for proper system flow and coordination.

Ideal for HVAC system design in residential, commercial, and industrial projects, this component is essential for connecting floor or ceiling registers to main supply or return trunks. It is frequently employed during the construction documentation stage to ensure accurate duct routing and clash detection in ceiling voids. Professionals searching for mechanical distribution components, duct transitions, or specific register boot fittings will find this geometry reliable for maintaining building information models that require high-fidelity mechanical system documentation and analysis.
