Bowmac B135s Post Bottom Bracket – Cast in

This Bowmac B135s Post Bottom Bracket is a Revit detail component designed for accurate structural documentation of cast-in connections. The Bowmac B135s is a professional-grade cast-in post bottom bracket, engineered for securing timber or steel posts into concrete substrates. This detail component provides a clean, precise 2D representation of the hardware, including the U-shaped bracket body, dual bolt fixings, and the integrated cast-in anchor leg with a splayed base for optimal grip within concrete. The linework is clean, intended for use in construction documentation and structural section details. It effectively communicates the mechanical connection between post and foundation, ensuring clarity for on-site assembly and structural verification in project drawings.

The download is a 276 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 Revit, load this RFA file directly into your project or drafting view as a detail component. Because it functions as a 2D family, it is best placed within section views or callouts where structural connections require specific annotation. Use the alignment tools to snap the component to your structural grid or floor levels. It allows for quick, consistent detailing across multiple project sheets without the overhead of heavy 3D geometry, keeping your file size manageable while maintaining high technical accuracy.
