Prime-line Products N 6704 Bifold Door Top Roller Guide

Product Description

The PRIME-LINE PRODUCTS N 6704 is a spring-loaded nylon top roller guide designed for bifold door installations. The roller sits in a 3/8-inch diameter plastic base and mounts to the top edge of the door, allowing the panel to travel smoothly along the overhead track. Each pack contains two guides. This hardware is used by carpenters, general contractors, and maintenance technicians to replace worn or missing bifold door hardware in residential and light commercial applications.

The N 6704 is suited for bifold doors that measure between 1 inch and 1-3/8 inches in thickness. It is a common replacement item in interior door hardware service, fitting the standard track-and-pivot bifold door systems found in closets, laundry rooms, and utility spaces throughout residential construction.
