Door Types
Horton Stack Doors
The framed opening height is the clear opening height — the Horton Stack door can save 2 ft. or more in overall building height.
Horton Stack doors install on virtually any type of building, saving money and space. The door mounts on the outside of the building — the Upper Guide Channel and Mounting Brackets attach to the flat header, as do the end hinges on the flat side jambs. Unlike vertical lift doors that store overhead, nothing is stored above the opening.
No motors are required; anyone can open this door with ease. Simply turn the handles located on every other panel, pull gently, and the Horton Stack Door glides on its bottom track to stack neatly out of the way. The stacking design allows for a complete or partial opening, eliminating the need for side entrance doors. Most installations are completed in one day.
The Horton Stack Door carries a one-year warranty on parts and workmanship; the manufacturer’s warranty on the fiberglass panel is a ten-year limited warranty.
