Bifold Finished Openings

Bifold Finished Opening Widths are true to the measurement (a 3/0 is 36”, a 2/8 is 32”, a 6/0 is 72”, etc). Doors will be undersized in width to accommodate the call-size of the bifold. Finished opening heights are based on standard interior frame components and clearances. If the bifold is shipped without a standard Frame, the Finished Opening may differ slightly. Most bifold hardware is adjustable in the field to accommodate different flooring thicknesses.
