Review: An amazing product but not a magic wand - This is an amazing product, especially if your alternative is replacing a large, heavy, expensive door, or continuing to live with a barely-functioning one. This product is not a brand new door, nor is it advertised as such. If you have other door issues, resolve them also. This simply repairs the existing damaged track. This is designed for minor damage. If you have severe damage or missing sections of old track, you may need to consider a more substantial product like CRL Aluminum 96" Sliding Glass Door Replacement Rail by CR Laurence . If you are not handy, you should not attempt to do this project on your own and then write a negative review on desertcart because you didn't know what you were doing. If you are not going to do it the right way, you probably should just hire a contractor to install a new door. Be careful with this repair track, it can have sharp edges. This is not a complicated project but you should at least have some concept of DIY projects. You must completely remove the sliding door (possibly both) from the track - this may be a task for 2 people depending on your situation. You should also replace the door rollers at the same time. They are usually inexpensive and you have to take the door out anyway to do this repair, at which point you can easily change the wheels. If your track was damaged, the wheels are probably damaged. If you reuse them on the new track cover, they will damage it. It's really pointless to repair the track and not replace the wheels. If you don't know what type you need, you will have to remove them to match them at the store. Before I started, I purchased 1 set of each type they had at Home Depot instead of leaving the door open to go to the store. I returned the ones I didn't need when I was finished. If the slot at on the bottom of the door has buildup or debris in it, clean it out with compressed air or a stiff brush. Clean your old track with a strong degreaser and a scrub brush. Make sure all the old grease, wax, dirt, etc. is removed before installing the new track cover. Make sure the track is dry. If you have severely damaged track, try your best to straighten it out - this can usually be done with visegrips or other strong pliers. If there are jagged edges or irregularities, use a file to clean them up. The purpose of doing this is to prevent the door from hammering the new track cover over the existing damage and replicating it. The repair track is stamped stainless steel. It has a thin coating of oil on it from the manufacturing process. Make sure to clean the underside with degreaser so the epoxy will adhere effectively. I wiped the underside of the repair track and the floor track with rubbing alcohol just to ensure they were clean and dry. Do not use silicone or caulking. Use this Loctite 2-part epoxy: Loctite Epoxy Five Minute Instant Mix 0.47-Fluid Ounce Syringe (1365868) . This is designed for metal surfaces and works very well for this project. Not only does it ensure a strong bond between the repair cap and the track, it also helps to fill in and harden low spots where the original track was damaged, providing support to prevent damage to the new cap. You will have about 5 minutes to work with this epoxy before it begins to harden. If you are prepared and organized, it should take you about 1-2 minutes to put the repair track in place. Wear rubber gloves in case the glue gets on your hands. The nozzle of the epoxy syringe is slightly wider than the repair track. I used pliers to slightly "squish" it and make it narrow so it fits right inside. Measure the repair track to ensure that it fits your door width. If it needs to be trimmed, you can do this with a Dremel, hacksaw, or cutting wheel. If you can do a dry/test fit, do so to get an idea of how it will go on once you are ready. If you trim a small piece off, temporarily dry install (no glue) this piece on the old track so you can see how it works. If you do this, take this piece off before the final install. When you are ready, apply a generous bead of glue to the inside of the repair track. If you have made the nozzle narrow, you will be able to get the glue directly onto the bottom of the repair track (the surface that will touch the old track). Keep in mind that you need enough to do the entire length and observe how much is in the syringe. I put a generous bead down the entire 8' length and only used 3/4 of the glue. Start on one end and gently press the repair track onto the old track. Depending on the condition of the old track, this may be easy or difficult. If it goes on easy with some room to spare, install the entire thing, then gently crimp it on with pliers. Take care to only crimp it enough to make it tight, not enough to deform the repair track. I crimped mine about every foot. If it goes on snug, you may have to use a rubber mallet or a block of wood and hammer to coax it into place. Be gentle - your goal is to get it on the old track, not deform the new one. Once it's in place, go back over the entire length and make sure it's all even and properly secured. If any epoxy leaked out, clean it up. Make sure none is on the surface of the repair track. I wiped the new track down with alcohol when I was done just to make sure. Install the new rollers in the door, making sure to adjust them low so you can get the door back in. Once the door is in place on the new track, move it back and forth to make sure it's not hanging up anywhere. Adjust the new door rollers. There are several videos on YouTube that show how to do this - it's very simple and will ensure that the door functions properly. Inspect the top guide ("track") - often if the old track was very damaged, the door may have caused damage on the top. If there are burs, gouges, or damage, they can usually be easily smoothed out with a file. Roll the door back and forth a few times in the first 5 minutes. This ensures that the repair track is properly and evenly seated when the epoxy hardens. Don't try to take shortcuts on this project. If you've been fighting with a damaged track for any amount of time, doing this project the right way will be well worth it. I worked alone, took my time, and was very thorough on my 8' sliding door. It took me less than an hour from start to finish.

## Questions & Answers

**Q: Track cover D1579-1 how many track pieces per pack?**
A: One piece, This track cover worked perfectly with brand new wheels clean it really well with a degreaser make sure there's no cleaner residue left on the old guide rail cut it about 1/4 of an inch longer silicone a small amount the entire length of new rail ,it will slip uder small space on jamb pull it forward and 1/8"under opposite jamb, close the door and put a small couple of tool boxes or some things that would weigh it down just lightly on the side that does not have the slider just overnight , door would not open without a lot of force before now opens with one finger

**Q: What is the exact thickness of the repair track?**
A: This item's wall thickness  is approximately .020 .

**Q: Triple door length is 105".  Left side rarely used.  How much of a transition will there be for the remaining 9" the wouldn't be covered?**
A: That's a tough question. The only really proper way to do this is to cover the entire track. However that being said, I understand not wanting to spend another $35 for a mere 9" out of 96". My doors are all triple panel but the L and R panels are fixed, and only the center one moves. My guess is you could see where the rollers on your doors are located (they are probably inset a bit from the edges of the doors) and see if the 96" will cover all the area in which the rollers touch. If this area is 96" or less, you are probably OK.

**Q: I ordered this item twice.  Both times it was undeliverable?  What's up here?  Anybody else having this same issue?**
A: I have ordered more than once and the 96” length is too long for the shipper to deliver without damage due to the spiral paper tube. I finally had to order two 48” pieces to receive them without damage.

### ⭐⭐⭐⭐⭐ Nice
*by A***. on January 7, 2026*

It’s easy to install and works great

### ⭐⭐⭐⭐⭐ Back on track!
*by G***N on October 26, 2025*

Our sliding glass door was installed at least 35 years ago. Over time the track became worn and bumpy making it difficult to open the sliding door. We were afraid a new door was going to be the solution until I looked on U tube and found the repair track video. I found the track on Amazon along with an installation video. It was easy to install and the door is like new. Instead of paying over $3,000.00 we paid under $40.00. Thank you Prime-Line.
