Prime-line Products N 6729 Bifold Door Top Guide Rod

Product Description

The PRIME-LINE PRODUCTS N 6729 is a bifold door top guide rod designed to keep bifold door panels aligned and tracking correctly within their pivot channel. The rod consists of a 5.25-inch steel pin fitted with a 3/8-inch diameter nylon cap that seats into the top track, absorbing contact stress and reducing wear. A hex nut and washer are included for secure threaded installation. This part is a staple hardware item installed by carpenters, finish trim contractors, and general maintenance technicians when servicing or replacing bifold door hardware.

This guide rod is used in Benchmark bifold door systems and is compatible with many other residential bifold door track configurations. It is typically installed in interior doorways where bifold panels are used for closets, laundry rooms, and utility spaces. The combination of a steel shaft and nylon cap makes this guide rod appropriate for standard residential interior door applications where a durable, low-friction pivot point is required.

Key Features

• 5.25-inch steel pin provides a rigid, stable guide shaft for bifold door alignment
• 3/8-inch diameter nylon cap reduces friction and wear at the top track contact point
• Threaded shaft with included hex nut and washer allows for secure, adjustable installation
• Sold as a single unit per card, suitable for single-panel replacement service
• Steel construction resists bending under repeated door operation

Compatibility

Designed for use in Benchmark bifold door systems and many other residential bifold door track configurations that accept a threaded top guide rod with a nylon cap.

Installation Notes

Installation is typically performed by carpenters or general maintenance technicians using standard hand tools. Before installation, ensure the bifold door panels are removed from the track to allow safe access to the top pivot channel. Thread the hex nut and washer onto the pin shaft and adjust to the correct height before seating the nylon cap into the top track guide. Do not over-tighten the hex nut against the door panel material, as this may cause cracking or distortion.
