Inside - no protruding parts 
The inside of the Crawford 542 has no protruding parts where tools could be misplaces, causing injuries when the door is opened.
When inside reinforcements are required, e.g. when a pedestrian pass-door is integraded in the main door, the design of the reinforcement is made in such a way that the risks above are reduced.

Finger pinch protection
The horizontal joints between the door sections are designed in such a way that fingers cannot be pinched during door movement.
Crawford offers different solutions to avoid pinch risks in the wall tracks e.g. roller shields and track covers.

Drop down protection
Crawford 542 is equipped with two special anti-drop devices as standard. They prevent the door from coming down in case of a spring or cable break.
