While BlackRock previously required that all two - dimensional artwork be hung from the gallery cable hanging system, we now most often use
alternative installation methods to include using hooks, nails, screws or other fasteners.
Applicants will be able to seek local approval through Section R104.11 «The provisions of this code are not intended to prevent the
installation of any material or to prohibit any design or
method of construction not specifically prescribed by this code, provided that any such
alternative has been approved.
