Prime-Line G 3119 Sliding Window Tandem Roller Assembly, 2 Pack

These rollers work very well, brass wheels are a nice upgrade from the original plastic ones. They do not have the locking tabs on the ends my originals had so a small bead of glue from the hot melt glue gun was necessary. An easy fix!

Work great, it was nice to have a window that rolled easily back-and-forth. I had to make a little shim as it was a little short on the length I used to piece of paper folded up a few times the same width as the rollers and cut the excess off and it was fine. They could’ve put a couple tabs in there, but I’m sure it fits multiple windows

Been using these to fix 30-year-old windows in my apartments for years. Good product.

Fits up easily. Does just what it is supposed to

Use these to replace a single wheel insert inside of my sliding glass double pane windows. They were slightly smaller so I used a small shim to make it fit. I already knew I would have to shim it, the size was just slightly smaller. The top has a flare so they can't fall into it, and with the shim giving it just a little bit more tension in the slot they're perfect. They've been holding up well with no problems at all and made all of my windows that I put them in slides so much smoother. Fantastic purchase, we'll be buying more to replace the rest in my house.

I had to return this item as it was a tad too small for my window. It was also missing the ears on both ends. I guess the picture doesn't show them so I ordered the wrong ones. I guess I will have to get out the dial calipers to get an exact measurement for correct part. This design seems very sturdy and looks like a better plastic housing.

Quality was OK, price was acceptable but when they copied the design, they didn’t include the snap in clip on each end of the housing. Without the snap in design, there is no way to hold these in the punched hole they are installed in at the bottom side of the window frame. If you are innovative enough to figure out how to hold them there while you replace the window into the track (without interfering with the rollers), you’ll be fine. A little dab of hot glue, etc should work. Once reinstalled the weight of the window will keep them in place. It was just a poor design by Primeline not to build them correctly.

Work real good with my project I was building, making cabinets with sliding doors, no track small enough for the cabinets i was making, made my tracks for the doors

3 years still works no problem

Worked perfectly, window is fixed 👌
