3750 Multi-Slide Doors

Innovative, Durable, and Low Maintenance. 



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.


You can reach our team in Dallas or in the Fort Worth area by phone at 214-329-0333 or 817-349-3334.
