Vertical
Drop Doors can be functional in the raised and lowered
positions.
The
primary advantage of a vertical drop door is the immediate
security barrier it provides whenever the
door is raised.
The
pictured bronze clad door for BVLGARI jewelers is
lowered into a pit below the sidewalk making it invisible
during normal shopping hours.
A
custom EPD hydraulic operating system raises the door
whenever the store is closed to provide an architecturally
pleasing security barrier.
