Our doors are designed to ensure the operating sashes slide quietly,
smoothly and effortlessly, year after year.

Patented tandem wheels in ultra-durable nylon leave no marks on the rail and provide smoothness of operation.

Our doors withstood 119,000 test cycles without failure, carrying a 165 lb. sash—the equivalent of over 30 years of constant use!

100% aluminum raised rail protects the wheels from damage or jamming caused by dirt and debris.
