CRL Monterey Bi-Fold Sliding Door Systems are a contemporary way to maximize the space available in residential or commercial properties, while at the same time creating stunning areas with brilliant transparency. Use this Bi-Folding Sliding Door System as a room divider or simply as a patio door. A pivoting door can be incorporated into the system, which works the same way as a traditional patio door, or the entire bi-fold system can be opened, leaving an enormous wide open space. Our Monterey Series Bi-Folding Sliding Door System can accommodate door configurations ranging from one to ten leaves and allows them to be stacked with minimum effort to one or both sides (with a maximum of five leaves per side). 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 and wood grain powder coated finishes. Custom finishes also available.
