Fireguard 从 Won-Door

Won-Door’s FireGuard™ accordion folding fire door has the ability to both serve as an opening protective in a means of egress AND as an access control device during after-hours events or off-hours lockdown. Design your new space using FireGuard + Access Control or retrofit an existing FireGuard door to have the best of both worlds – a fire-rated opening protective + an access control device.
