The PurOptima 117 Plus is a single-glazed wall partition system that can be used to make private rooms out of open spaces. Minimal head and base channels and discreet glass-to-glass dry joints create the illusion of vast areas of unsupported glass. The aluminum base channel can either be 25 millimeters or 50 millimeters deep. Where deflection is required, the base channel is 36 millimeters wide to align with the deflection head channel, but if there is no deflection the base channel is just 25 millimeters wide.
