Slide-Co 13808-S Sliding Patio Door Roller Assembly, 1-1/4 In. Wheel Diameter, Steel Ball Bearing Wheels (Single Pack)

They were exactly what I ordered. Caution to those who are installing them. You need to know where your adjustment screws are located on your door. I knew these were in the front while my existing door had them on the side. Being a contractor it was easy for me to measure, drill new holes in the front and use a plastic plug for the new holes (really don't need the plug covers, I am just anal). I had an older custom slider. Really couldn't find the same replacements. These were great, sized perfectly and adjusted nicely. Door slides nice again and the wife is VERY HAPPY ; )..BLW that door is opened and closed a million times a day with 3 dogs. Pretty fast shipping also.

This went right in place, one-for-one. Our sliding door had been a problem for some time and we thought we were going to need to replace the whole thing. Turns out that one of the wheel sets had corroded and locked up. Such an easy replacement and now the door works like new.

For months we had been trying to convince ourselves that the problem was everything except the rollers/wheels. The sliding glass door to the backyard was sticking and tilting. It was like trying to move a mountain by yourself to open it. Our door gets a lot of use. There's a pool, a gas grill, a gazebo, a hot tub, a tiki bar, and a couple of lounging areas. The backyard is our oasis and sanctuary. All of that became extremely difficult to access for adults and impossible to access for young children and elderly family members due to the problematic sliding glass door. We also have dogs that must be let out and back in several times per day. For the six years since we moved in, we had trusted that the sliding glass door would grant us passage out and in, but then it decided to act like a brick wall.It must be a dirty track, we thought; so we cleaned the track several times. It must be lubrication, we thought; so we routinely sprayed the track. Then it's out of alignment, we thought; so we adjusted the roller/wheels up and down trying to find the "sweet spot" that had disappeared several months ago. Wrong, wrong, and wrong.After achieving only small and very temporary improvements, it was decided to replace the rollers/wheels. The hardest part of installation was removing the sliding glass door from its track, but even that was easier than trying to open the door and took maybe a minute or two. Replacing the rollers/wheel took moments and reinserting the door into the track was another minute or two. So a few minutes after starting the installation project, we tried the door. There were stages to the joy that swept through us. First, came the disbelief. Everyone tentatively tries the door because the ease of opening it went from hernia-causing for some and impossible for others to a single-finger operation. Then came realization that finally the correct solution had been identified and implemented. A wave of embarrassment washes over because it was so simple and obvious--though this had escaped these first-time homeowners. Finally, acceptance and joy settles in and all is good. Only a few people experienced our struggles due to social distancing and limits on gatherings, but we already plan to casually acknowledge, "yes, we finally just put new rollers in," should anyone mention it. We'll act as if we knew all along that it was the rollers/wheels.We can't compare these rollers/wheels with any others because these were the only ones we've needed. These were chosen because of reviews testifying sturdy metal construction and the mention of ball bearings in the title.

Inexpensive way to repair the sliding motion on an old patio door that was still in otherwise great shape. Much cheaper than replacing the door. Fit the existing opening perfectly. Glides easily. Did require an adjustment already to raise the door making it glide easily. Hope it lasts.

Outstanding product. No fit issues as was reported with similar products. Works great on my old Anderson sliding door. Only regret is not buying it sooner

I guess my sliding door is unusual as what I got was perfect other than the tabs/flanges where you insert the screws to the bottom of the door. If you look @ picture of what I got, flip those flanges at the ends for the screws 180 degrees to the top vs. bottom of wheel assembly, that is what I needed. I did measure what I had & compared to measurements Amazon gave me & it was perfect...but I missed the flange position. I ended up doing a lot of work taking my old roller assembly apart, rebuilding wheels/bearings & putting back together. I could not find a roller assembly EXACTLY like mine?So, it didn't work, why 5 stars? It was guaranteed for return & feel like I was partly to blame? I was given no problems, sent it back & quickly refunded. I did have to take it to a UPS store, but didn't have to package or label anything, just hand it over & let them scan QR code on my phone. OK, I happen to have a UPS store within 2 miles of where I live, but it was so easy once I got there & on a route I often take.

Direct replacement for my sliding door. Local hardware store does not stock them. Took 30 minutes to pull out sliding door (which is larger than most). Installed new roller assembly with same hardware. Real nice. Now my door opens and closes with one finger!

My sliding door was not rolling proper so I bought these to replace my 14 year old ones, until I pulled my old one off and compared the quality. The old ones were way higher quality and heavier. I cleaned the old ones and moved on.
