Prime Line Products N 6703 Bi-fold Door Roller Guide 2 Pack

Product Description

The PRIME LINE PRODUCTS N 6703 is a spring-loaded bi-fold door roller guide sold in a 2-pack. It is designed to mount on the top edge of a bi-fold door panel, fitting into a 3/8 inch diameter hole to guide the door smoothly along its track. The guide features a 7/8 inch outside diameter wheel that is 1/4 inch thick, seated on a 3/8 inch outside diameter base. Components are constructed from steel, nylon, and plastic for a combination of durability and low-friction operation. This hardware is installed by finish carpenters, general contractors, and experienced DIYers when replacing worn, missing, or damaged door rollers.

These top-mounted roller guides are a direct fit for Kenna Frame bi-fold door systems and are sized to work with many other manufacturers that use the same guide specification. They are suited for residential interior bi-fold doors, including closet doors and passage bi-fold applications. The spring-loaded design maintains consistent contact with the track, helping to restore smooth and reliable door operation after a roller has failed or gone missing. Package quantity from the supplier file is 6 units per case, with individual packs containing 2 guides each.

Installation Notes

Installation is typically performed by finish carpenters or experienced general contractors as part of a door hardware replacement. Before servicing, remove the bi-fold door from its track to avoid injury. A 3/8 inch diameter hole in the top edge of the door panel is required for guide insertion. Inspect the track channel for damage or debris before reinstalling the door to ensure the new guides operate properly.
