Bi-Fold Door Bottom Pivot, 1/4'' Pin x 3/8'' Base, Steel 2-PK, Prime-Line MP6613 The Prime-Line MP6613 bi-fold door bottom pivot is a heavy-duty, zinc-plated steel assembly engineered for smooth, stable operation of steel-framed bi-fold closet doors. Designed as a complement to top pivots, this pair of screw-in bottom units provides critical vertical support and alignment, preventing door sag, binding, or misalignment during repeated opening and closing cycles. Each pivot features a solid 1/4-inch steel rod with a 3/8-inch base, housed within a durable steel clip and spring-loaded mechanism that allows slight vertical movement ? reducing stress on hinges and tracks while ensuring quiet, consistent motion. The corrosion-resistant zinc finish enhances longevity in dry indoor environments, making it ideal for bedrooms, closets, and laundry rooms where reliability matters more than aesthetics.

Paired with a matching top pivot (such as the N 6612), it creates a balanced, four-point mounting system that eliminates wobble, binding, and uneven wear ? common issues with worn or mismatched hardware. Its spring-loaded design allows the door to rise slightly when opened, lifting it off the floor track to prevent scraping and reduce friction. Ideal for homeowners repairing aging wardrobes, contractors upgrading multi-door installations, or DIYers building custom storage solutions, this pivot delivers professional-grade durability with simple tool-free installation. Use in bedrooms, walk-in closets, pantries, or utility rooms where frequent use demands long-term performance. A trusted component in legacy systems and new builds alike ? built to last, not replace.
