Cotterman Roof Ladder with Cage and Walk-Thru Railing

This Revit family provides a high-visibility yellow steel fixed roof ladder, featuring an integrated safety cage and walk-thru railing. Engineered for industrial applications, this fixed vertical ladder assembly includes a robust steel frame finished in a high-visibility yellow coating. The design incorporates a protective safety cage that begins above the lower ladder section, providing secure vertical transit. At the upper termination, a walk-thru railing system allows for safe transition onto roof surfaces. The assembly is supported by wall-mounted brackets, ensuring structural stability for exterior or interior vertical access. The geometry is clean and functional, prioritising safety and compliance with standard industrial access requirements for maintenance and roof servicing.

The download is a 778 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 into your Revit project as a wall-hosted family. Once placed against the desired vertical surface, use the instance parameters to adjust the total height to match the building structure. Ensure the wall-mounting brackets are correctly aligned with your structural face. Use the visibility graphics settings to toggle the cage or railing components if necessary for specific technical documentation or coordination views, and apply a material parameter to control the finish colour for visualisations.
