A Door Nearly Four Times as Wide as It Is Tall
This project has two bifold doors, each 41 feet wide and only 11 feet tall. On a 41-foot door, the lift straps are spaced evenly to spread the weight across the width. Each lift strap is rated for 29,000 pounds. The straps wind onto spools on one drive system, so they pull together to lift the door easily and keep it level from end to end.
Open, closed, or partway up, the door stays tight against the building thanks to its bifold design and strap latches. Even on a windy day, you can open the door as far as you want for fresh air, then latch it closed for a secure seal every time it shuts.
