Horton Stack Doors by Duro Buildings

Duro Doors is an established distributor of Horton Stack Doors. All the weight of the Stack Door is on the bottom track, unlike the bi-fold door, which carries the weight of their door overhead. That means a savings to you because of the extra expense required for the building manufacture for the end wall loading needed to accept the weight of the bi-fold door.

Horton Doors are for large openings - up to 70'

We also offer Commercial Overhead Doors, Insulated Doors & Electric Operators

Stack Door is manually operated door system, that glides on patented truck assemblies located on every other panel. Each truck assembly has 6 heavy duty sealed bearing, two riding on the top of the track and two riding one each side of the track. This design eliminates friction on all three sides of the bottom track, for a smooth operation. Due to the fact that power operators are not required, you eliminate the problems
