The PRIME-LINE PRODUCTS N 6672 is a nylon top pivot guide designed for bifold door installations. The spring-loaded pin measures 3/8 inches in diameter and inserts into the top pivot bracket to create a stable pivot point at the top of the door panel. Each card contains one pair of pivot guides. This hardware is a standard component in bifold door track systems and is typically installed by carpenters, finish contractors, or experienced DIYers performing door hardware replacement or new installation.
This pivot guide fits standard residential bifold door applications where the top pivot bracket is already in place. It is suited for interior bifold doors commonly found in closets, laundry areas, and utility spaces. The nylon construction resists wear and operates quietly, making it appropriate for high-cycle residential environments. Install as a replacement for worn or broken top pivot guides or as part of a new bifold door hardware setup.
Designed as an OEM-style replacement top pivot guide for standard residential bifold door track systems where a top-mount nylon pivot bracket is used.
Installation is performed without specialized trade licensing and is within scope for general carpenters or finish contractors. Remove the door panel from the track before replacing pivot hardware. Ensure the top pivot bracket is securely fastened to the door frame header before inserting the pivot pin. Confirm the spring pin fully seats and retracts smoothly before reinstalling the door panel.
