A1’s 350 Series over sized patio doors are a key feature throughout the space; allowing easy access to roof top balconies. Long term dependability and smooth operation is assured through use of dual tandem rollers and weather sealing on all perimeters.

This unique double slider configuration allows the homeowner to choose which side of door to open dependent on the prevailing breeze. The configuration is also ideal for smaller spaces where furniture placement might play a role in which side to open.
