Crown Door's hydraulic folding doors offer a smooth operation and a sleek look with just one press of a button. These can be designed to match your exterior cladding so it will flow with your building's facade.
For the smaller openings such as counters and window openings, the SST-II uses electric actuators instead of hydraulic cylinders with a better price point in mind. These doors are even great for residential applications where you want to bring the outside environment in to your home! These are made up to a 8' wide x 6' high.
