J-strap bifold hardware for industrial interiors — the visible curved strap and roller bring the same hardware-forward character of industrial single track installations to bifold configurations where wall clearance is limited. Available in matte black across standard duty Goldberg Brothers, heavy duty Goldberg Brothers, and house value line. Two-door and 4-door biparting configurations. For industrial single track and bypass hardware, see our industrial hardware kits collection.
Choosing the right industrial bifold kit
- 2-door bifold — two panels fold to one side. Approximately 5 in (Goldberg Brothers) or 6 in (house value line) of stack on the pivot side. Covers openings up to 93 in.
- 4-door biparting — four panels split symmetrically, two to each side. Approximately 5 in of stack per side. Covers openings up to 188 in. Alignment plates included where panels meet at center.
- Standard duty — panels up to 125 lbs total (2-door) or 250 lbs (4-door biparting), door thickness 1-1/4 in to 1-3/8 in.
- Heavy duty — panels up to 400 lbs total (2-door) or 800 lbs (4-door biparting), door thickness 1-3/8 in to 2-1/4 in. The right choice for thick reclaimed wood or solid hardwood panels common in industrial spaces.
Handles are included with all Goldberg Brothers bifold kits, color-matched to matte black. House value line kits do not include handles. Soft close is not available for any bifold configuration.
