Prime-line Products N 6584 Bifold Door Bottom Pivot

Product Description

The PRIME-LINE PRODUCTS N 6584 is a bottom pivot guide designed for residential bifold doors. It consists of a 7/16-inch diameter nylon base housing a 3/16-inch steel pivot pin secured with a hex head nut for field adjustment. The nylon base resists wear and reduces friction at the floor track, while the steel pivot provides the load-bearing strength needed for repeated daily use. Licensed tradespeople and skilled DIYers install this pivot as part of a complete bifold door hardware set. It suits doors weighing up to 30 pounds each and accommodates door thicknesses from 1 inch to 1-3/8 inches.

This bottom pivot is suited for standard residential bifold door installations in closets, laundry rooms, and utility spaces. It anchors the lower corner of the door panel into the floor bracket, allowing the door to swing and fold smoothly along its track. The included hex head nut allows installers to fine-tune the pivot position after mounting, which is useful when aligning door panels on uneven floors or in retrofit situations. Sold in a pack of 2, this hardware supports a single bifold door unit requiring one pivot per panel bottom.
