How to Repair Bifold Door Top Roller Guide

If your bifold door is sticking it's likely they require some maintenance. It is possible that you need to clean, lubricate or adjust them. The issue could be caused by an unfastened bolt on the top pivot, or by the top guide roller.

This kit includes all the hardware you need to restore your bi-fold wardrobe door system to its best performance.

Take the door off

It may seem complicated and difficult to install an internal set of bifold doors but for those who are DIYers with some experience, it is actually quite simple. The frame isn't the issue however, getting the doors to close and fold smoothly is. As bifold doors are complex machines, they could require some tweaking to ensure they are working properly. This might be something as simple as tightening a screw or as complex as taking out the door and replacing the pivot pin or roller.

You can usually fix these problems with just a few minor adjustments, without the need to take off the doors. It is possible that your bifold doors are sliding, scraping the floor or jumping out of track. The solution to these issues isn't a big deal, and with three simple steps your bifold doors can be back on track in short time.

One of the most frequent problems that internal bifold doors encounter is sliding out of alignment. This can be due to loose screws, holes in the anchor/pivots, or a misaligned bifold door. The majority of the time it can be fixed by making a few minor adjustments. However, if your door doesn't move in any way, you might have to replace it.

You'll have to take off the door with a screwdriver, and possibly an plier pair to loosen any pivot pins that are too tight. The screwdriver can be used to disengage any locking levers that are on the bottom pivot bracket, and the pliers will allow you to wiggle the pin and take it off.

After the top roller has been removed, you can lift the door, swivel downward and remove it from its track and pivot brackets. It's usually quite simple, but be careful not to let the door slam against the door frame. Then, you can sand down the edges of the door to make it smooth. You can then paint or refinish the door if required.

Remove the Roller Guide

This spring-loaded roller guides the mount on the top of a bifolding door to facilitate smooth operation. It is specifically designed to work with Kenna frames, and will fit door panels that range from 1 inch to 1-3/8 inches thick. It is made from nylon, steel and plastic components. It can be used to replace a worn-out or damaged guide.

Remove any screws holding the roller guide in place by using a screwdriver. Use your hands to carefully lift it off the frame. It might require some effort to take off the door, so ask someone else to assist you.

After the guide has been removed, carefully cut the remaining finish on the foot of the new guide using a sharp blade to remove it from the rod blank. This will make it easier to remove and will protect the new guide foot. The guide foot is extremely sharp, and it can cut or snag fingers.


It is possible to use some force to remove the guide, but you must be careful not to chip or break the foot. After you've removed the guide from the rod blank, make sure to remove all of the threads and epoxy remaining in the area where it was attached. This will help prevent any future problems with the guide.

After removing the previous guide, you can test the replacement by placing it in its new location. Make a few turns with masking tape or guide tubing to secure it in its place. This will allow you to double examine the guide's spacing and alignment to make sure everything is set up properly. This is vital to avoid future problems, whether you use the CRB Spine Finder and Deflection System, or eyeball it.

The last step is to replace the door. If the guide is in the proper position and functions in the correct way, then you're ready to proceed. Make sure that any screws or pins were removed or loosening must be replaced and tightened appropriately when you're finished.

Take the Bottom Pivot off.

Bifold doors can be a stunning addition to any home, but they often need to be tweaked or adjusted to keep them in good working order. Some issues can be addressed by keeping the doors in place. Others will require the doors be removed. This guide will demonstrate how to remove the bifold internal door pins, rollers, and pivots.

Gathering your tools is the first step. You will save yourself some frustration if you gather all the tools you need in advance. You'll need a screwdriver, pliers and maybe a wrench. A basic set of tools can be bought at a reasonable cost at your local hardware store. Keep some wood glue on hand. This is useful in the event that you have to put the rollers in their place.

Once you've collected your tools, begin by opening the bifold doors and then loosening the top track bracket with your screwdriver. Once this is loose, the door should be free to slide off the top track completely. It might take a bit of shaking to get it there, but it should come off the track.

The pivot at the bottom of the frame will need to be removed. Close all doors in the interior before you begin. This will make it much easier to do than trying to work from the inside. If the bottom track still appears to be in good condition it is possible to raise the door to take off the track.

If the track is damaged, then you'll need to replace it. Hardware stores offer replacement tracks for bifold doors as well as swinging closet doors. If the track is badly damaged, then you might need to replace it completely.

You'll now need to test your doors to ensure proper function. Check that they're capable of moving smoothly in and out of position. You'll also want to check that the edges of the door are parallel to the frame when closed. If they're not, you'll need to adjust the top pivot bracket by tightening or loosening the bottom screwscrew.

Replace the Roller

Bifold doors can be used to neatly cover closets as well as laundry nooks and pantries, but only when they function correctly. They consist of two door panels that are hinged together and open up on tracks that are positioned in the frame's top. Over time the roller guide bearings could wear out, causing the doors to slide and scrape against the floor. Replacing bifold door repair requires only a few minutes, and the most basic tools.

The first step is to take the guide for the roller from the door panel. This involves removal of the bottom pivot bolt and loosening the screw that holds the guide to its top. After removing the guide, lift the panel out of the track. Next, loosen the nut that secures the top pivot bolt and use the wrench to remove it from the hole in the top header of the door frame.

A top nylon replacement guide with a 7/8 " diameter wheel and a steel base is available from Stanley, Cox or Acme. It can be mounted on the top edge of bifold doors that range from 1 inch to 1-3/8 inches in thickness and is spring-loaded to adjust in the upper track for smooth sliding.

A bifold door can also scrape against the floor as it closes and opens. This is often the result of adding carpet or other flooring materials which require the doors be raised slightly to allow for clearance. This issue can be fixed by getting rid of the screws that adjust the bottom pivot by loosening the top track mounting screws and moving the anchor/pivot.

A new set top roller guides could be a low-cost solution to the problem of your bifold doors being difficult to operate. They are typically found at your local hardware shop in the door section. However they can also be purchased online from several vendors. You'll also require the squeeze-clamp and a tiny container of Elmer's wood adhesive which is available in large box stores. The clamp is used to keep the repair area tightly closed after the glue has been inserted and allowed to dry.
