Prime Line Products N 6705 Bi-fold Door Top Guide 2 Pack

Product Description

The PRIME LINE PRODUCTS N 6705 is a nylon bi-fold door top guide sold in a 2-pack configuration. This hardware component fits into the top track of a bi-fold door assembly, keeping the door panels aligned and allowing smooth travel along the track. It is a direct replacement for worn or damaged top guides on Alliance bi-fold door systems. Installation is typically handled by carpenters, general contractors, or maintenance technicians performing door hardware service or renovation work.

This top guide is suited for residential and light commercial bi-fold door applications where the existing guide has cracked, worn down, or gone missing entirely. The nylon construction resists corrosion and provides low-friction contact with the track channel. The 2-pack format covers a standard single bi-fold door unit, which typically requires two top guides.

Key Features

• Nylon construction for corrosion resistance and smooth track operation
• 2-pack quantity covers a standard single bi-fold door installation
• Designed as a replacement top guide for Alliance bi-fold door systems
• Carded packaging for easy retail and jobsite identification

Compatibility

Designed as a replacement bi-fold door top guide for Alliance doors. Confirm track channel dimensions and guide profile against the existing hardware before installation.

Installation Notes

Installation requires no special tools beyond basic hand tools. Remove the door panels from the track before replacing the top guide to avoid panel damage. Ensure the replacement guide seats fully into the top track channel before re-hanging the door. Follow the door manufacturer's hardware replacement guidance where available.
