Prime-line Products N 6673 Bifold Door Bottom Pivot 2 Pack

Product Description

The PRIME-LINE PRODUCTS N 6673 is a bottom pivot assembly for bifold doors, designed to provide a stable and adjustable pivot point at the base of the door panel. The unit features a nylon base with a 3/8 inch diameter and houses an adjustable steel pivot tip with a grooved profile. The pivot bolt measures 1-3/8 inches in length with a 15/32 inch outer diameter. The grooved tip threads in or out to fine-tune door alignment without removing the hardware. This type of hardware is installed by carpenters, general contractors, and maintenance technicians working on residential or light commercial bifold door systems.

This bottom pivot is suited for standard bifold door installations where the existing pivot hardware requires replacement or where a new door panel is being hung. The adjustable design accommodates minor floor-to-header height variations, making it practical for retrofit applications. Each pack contains two pivot assemblies, providing enough hardware for one standard bifold door pair. The nylon base resists corrosion and reduces friction at the floor track interface during door operation.

Compatibility

Installation Notes

Installation is performed by carpenters or general maintenance technicians using basic hand tools. Ensure the door panel is safely supported before removing the existing pivot hardware to prevent the panel from falling. Thread the pivot tip to the appropriate height before inserting into the floor bracket, then fine-tune alignment after the door is hung. Follow applicable building and finish carpentry guidelines for bifold door clearance and track alignment.
