There's no need to increase the height of the entire building or add a support above the roof line, as is often necessary with standard bi-folds, to make-up for clearance lost when the door is fully open.  Patented auxiliary arms on the Hi-Fold Door enable it to open to within 10 to 28 inches of the hinge mounting line without putting undue stress on the jamb posts.

Save material and labor on new buildings!

High-clearance advantages of Hi-Fold Doors enable you to trim new building costs in four important ways:

1. Column lengths can be shorter

2. Less skin is required

3. Fewer fasteners are needed

4. Your crew's work time is reduced.

These savings, alone, can pay for the Hi-Fold Door.

Retrofit existing doors without losing clearance!

With Hi-Fold Doors, you can replace worn-out or hard-to-operate sliding and overhead doors or cover door-less openings on existing buildings, while adding the convenience of bi-fold doors, without sacrificing door opening clearance. In-place headers are normally adequate for mounting Hi-Fold Doors and building modifications, if any, are minimal. Side-wall doors can also be installed without changing the roof line.

Hi-Fold Doors keep bad weather out! The Hi-Fold Door is unaffected by weather extremes. When fully open, it forms a canopy over the opening for protection from sun and rain. When closed, sturdy jamb latches and a durable bottom seal keep out foul weather and intruders. The center hinge folding action and high-strength cable lift system pulls the door up and away from build-ups of ice and snow to assure efficient, year-around operation.

Hi-Fold Doors can be easily insulated by surface-mounting board or blanket insulation prior to installing the skin. Additional insulation can also be inserted between the grid members. Walk doors and windows, in a variety of attractive styles and sizes, can be added to provide easy access and natural interior lighting.
