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!

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

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

Perfect fit

Fits up easily. Does just what it is supposed to

Like others say it does not clip in like it should, probably could have used hot glue, instead I got the rollers from the manufacturer, and through these away. So I decided to give them an neutral rating of 3 stars.

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.

These brass wheels looked to be the correct dimensions, however, they are ever so slightly smaller and without the locking tabs on either end of the length which hold the wheels in place. These do not lock in making them slightly smaller therefore they don’t “snap” in place.

3 years still works no problem

Worked perfectly, window is fixed 👌
