HD Sliding Glass Door Rollers

Thanks for writing in! Your tandem roller from Ultra is no longer available, unfortunately. The good new is, we do carry the 81-044 single wheel roller with the same dimensions. However, it only has one wheel. We are not confident it will properly function under the weight of with your 8' doors but it may be worth considering as a replacement. 

You can also take a look at the 81-056 tandem roller. We carry it with a 1-1/4" or a 1" wheel, but it's housing is a little thicker at 11/16".

Take a look over the dimensions for both rollers below. See if either of these could be a fit for your door.
