Win-Dor's innovative, durable and low-maintenance 3750 Series multi-slide door system is considered among the highest quality multi-slide doors in America.
Our multi-slide doors are extremely energy efficient, very strong and structurally sound. Our unique blend of rigid aluminum framing with a long-lasting, low maintenance vinyl capping creates a unique combination not available from other manufacturers.
We offer a very clean 3 3/4" x 13/4" sash which measures the same as our folding doors. This allows for a consistent look when mixing and matching systems in the same home. Our 17/8" rollers coupled with our extruded track system allows for easy operations when opening and closing.
