Sur­face-mounted overhead door closer with scissor-action arm

The GU overhead door closer types with scissor-action arm are desi­gned for 1-leaf inte­rior and exte­rior doors, and also for fire and smoke pro­tec­tion doors. They are easily mounted, flexible, and individually adju­stable. Due to their out­standing func­tional relia­bility, the clo­sers can be mounted both on the hinge side and oppo­site to the hinges.
