These 4 highly integrated structures were engineered to support critical glass and all electricals for information wiring. Back painted, 1/4" tempered glass. All reveals are held at 2mm. The four individual Tech Displays are paired end to end creating two continuous cases that appear to float, as there are no kicks. Each display unit has a hidden door weighing 85 lbs. Doors unlatch from below and roll open to a 90 degree stop on industrial casters.
