Edit the Top Rail of a Guardrail in Revit

[@ThomasPilkington-gt2zu]

Thank you so much Tab + click, enabled me to edit top rail to my custom profile.
For some stupid reason when you click on the rail as a whole and then edit type in properties, custom Top Rails do not appear in the drop down, but they do appear in Rail Structure (Non-continuous)
