The Solid Mount® only uses 14 parts to create the strongest mounting bracket made for fiberglass enclosures. We start with a proprietary mix to create a 6000 psi material which is the heart of The Solid Mount®. The Solid Mount® is then attached to the studs of your home using a 5/16″ dia. lag bolt. The grab bar is then mounted to the Solid Mount® with 6 Specialty screws.
