Unfortunately we do not currently manufacture a rail bracket that is designed to work with wrought iron railings. We have had a few customers let us know that they have been able to modify the installation of our current deck rail kits to work for this function. Photos below of this modification.
Again, this isn’t something we’ve tested ourselves; however, according to our customers the installation seems pretty secure. We cannot recommend this application and certainly can’t be responsible if it doesn’t work.
It is up to each individual customer whether or not they'd like to give it a try!
