Long Life, Low Maintenance
Bi-fold or sometimes called Four-Fold doors are a good choice when side space is available and there is a need for long lasting low maintenance doors. There are no springs to break and jamb the door.
Speed
Bi-Fold doors on average open faster than a typical overhead door often twice as fast. Typical speeds of 24 inches per second compaired with 8 to 12 inches per second for other door styles.
Size
Four-fold door sizes range from 7’ x 7’ by 24’ x 24’, with larger sizes available
for special applications. 
Horizontal Movement
The Four-Fold door moves horizontally rather than vertically. As a result, the door is visible throughout the opening motion. And bi-fold doors are tolerent of dents and dings from impact in that the door will still close.
Maintenance
With regular maintenance Bi-fold doors are designed to perform over 1 million cycles.
Manual Operation
Since no springs are required, the Bi-Fold door’s manual operation is quick and easy with the simple pull of a cord.
Save Time.
