Replace any existing door with a Diamond Bi-fold Door and save 10%

For the month of April, any door installed on an existing building will be 10% off. Now is the time to upgrade your quonset, shop or storage building.


With the Diamond Bi-fold door, you can extend the opening width and height, utilizing our self-supporting header system. Mounting to the exterior of the building, this feature allows the door to be extended past the roof line and provides a larger clear opening. Add options like a pedestrian door, windows, polycarbonate, or auto-lock system for the ultimate upgrade.

Promotional pricing applies to retrofit (existing building/replacing existing door) projects only.
Discount applies to door and options only, shipping and taxes are excluded.
Orders must be placed by April 30, 2021 to qualify.
This promotion is not valid with any other offer or discount.
Some conditions may apply to specialty projects. Valid to USA and Canada.
