Our Monterey Series Bi-Folding Sliding Door System can accommodate door configurations ranging from 2 to 26 panels and allows them to be stacked with minimum effort to one or both sides, leaving an enormous wide open space. A pivoting door, that will also fold up with the entire system, can be incorporated into many configurations. Design options are virtually limitless. The sturdy, yet slim frame construction allows for more glass and less metal. The Monterey Series is designed for 1/4" to 1-1/4" (6 to 32 mm) glazing thickness, and the frames are available in white, black, and wood grain powder coated, satin and black bronze anodized finishes as standard with custom finishes also available.
