Easy install.

Part number on them.

The most difficult part of replacing patio door rollers is identifying the right model. That requires removing the door, pulling the rollers, reinstalling, putting it back together then ordering. These were a perfect match and came overnight. The second most difficult part of changing the rollers is knowing how to remove the rollers. Most patio doors needing repair are ten or more years old and do not come with instruction manuals. And, in our case, you can not identify the manufacturer. This product would have gotten five stars had it contained some basic instructions that helped us go in the right direction. A YouTube video would have been better. Yes doors vary but not that much. Our door now slides with fingertips, in fact, almost too easily. It is great.

Good quality. Could not get wheels over plastic edge. Open door 💯 and lift up and in. Mark wheels location with marker, use die grinder to grind out plastic where I marked all four wheels. Lift door back up and align wheels with ground out spots and gently push wheels on the track. Make sure to have the door open all the way too mark and grind.

Easy to replace, mine were model 10 but we're an exact replacement. Wish I would have done them sooner. Make sure to clean the track really well with a strong degreaser.

These were delivered in 1 day. The wheels on the old set were gunked up and frozen. I watched a video or 2 on how easy this was. It was not. Our slider had very little clearance even with the wheels raised. After lots of prying and colorful language I finally got the door with the new wheels popped back in place. One thing for sure is I will never let the track get dirty again.

The left side roller went out on my sliding door. I ordered this one and was amazed at the quality of the roller received. I wish I took a side by side picture to show the metal is solid, the wheels are sturdy and overall this roller made a huge difference in closing and opening my door. What use to take two hands now can be done with a finger. If your door is hard to open, this is the rollers for you.
