A reoccurring question that we at Hi-Fold run into is what the differences are between our standard bi-fold, our high-clearance bi-fold, and our no-fold single-panel hydraulic hangar door products. Are there any advantages of one over the other? The good news is there is never a wrong choice, just choices that may be more beneficial depending on the application.
Higher Clearance
Highest clearance of any other bi-fold door on the market
Patented Auxiliary Arms allow for 12-24" more clearance than a standard bi-fold door
Good choice for retrofit if the building is shorter in height, or there is limited space between top of door frame and roof line
Standard clearance bi-fold door
Best option if building is taller, with ample mounting space between top of door frame and roof line
Overhead clearance when fully extended is 5" less than building rough opening
Comes with it's own frame that mounts to building opening, so does not require space between top of door frame and roof line
