you need to protect an opening that is larger than 72" in either
direction (such as a sliding glass door), it will be necessary to
utilize more than one panel. We suggest either utilizing a field
engineered "H" coupler or using one of our rigid Polycarbonate "H"
Couplers to join adjacent panels that abut one another and to provide
center support. The process involves anchoring the coupler at both the
top and bottom and then sliding each panel into the opposing "throats"
of the coupler until each is firmly seated therein. If the bottom of
the coupler is at the top of a slab or other flat surface, we offer an
"L" bracket that can be used to anchor the bottom. In either case, we
suggest anchoring each of the panels very close to the "H" coupler to
provide additional stiffness and support.
