Prime-line Products N 6703 Bifold Door Top Roller Guide

Product Description

The PRIME-LINE PRODUCTS N 6703 is a spring-loaded nylon roller guide designed for the top edge of bifold doors. The roller measures 7/8 inch in diameter and seats in a 3/8-inch diameter plastic base. This guide keeps bifold door panels tracking correctly within the overhead track, preventing lateral drift and off-track binding. It is a direct hardware replacement installed by carpenters, general contractors, maintenance technicians, and experienced DIYers working on interior bifold door assemblies. The pack contains 2 roller guides.

This guide is suited for residential and light commercial bifold door installations. It mounts to the top edge of bifold door panels that are 1 inch to 1-3/8 inches thick, covering the standard door thickness range found in most interior passage and closet applications. The spring-loaded design allows the roller to seat firmly into the overhead track without requiring precise vertical adjustment during installation.

Key Features

• Spring-loaded roller maintains consistent contact with the overhead track
• Nylon roller construction for smooth, low-friction operation
• 3/8-inch diameter plastic base mounts directly to the top door edge
• Compatible with door panel thicknesses from 1 inch to 1-3/8 inches
• Pack of 2 guides for a standard single bifold door unit

Compatibility

Designed for bifold door panels with a top edge thickness of 1 inch to 1-3/8 inches. Fits standard residential and light commercial bifold door track systems that accept a top-mounted roller guide with a 3/8-inch base diameter.

Installation Notes

Installation is performed by carpenters or maintenance technicians using basic hand tools. Remove the door panels from the track before installing or replacing roller guides to avoid injury and to allow proper seating of the base into the door edge. Verify the overhead track slot width is compatible with the 7/8-inch roller diameter before final installation. Re-hang the door panel and confirm the roller seats fully into the track before testing operation.
