Braced Arm Canopy Doors
For openings of any width and up to 80' high. The use of one or more independent horizontal sections side by side makes the Braced Arm Canopy Door ideal for any width opening. Each section is an average of between 60' and 80' wide, and may be operated independently or in combination. The bracing system distributes wind loads into the building framework, guiding door movements without a need for jamb or side guides.
