The Bypass sliding barn door hardware is efficient in tight spaces, offering a low profile alternative to the bulkier designs. The ability to slide one door over another makes the Bypass effective for closets, or multiple openings on the same wall.

Fabulous solution when space is too tight for a standard hinged door. You can also put furniture on the walls next to this opening, just leaving enough space behind the furniture for the doors to slide.
