disco 2002 tandum 1 1/2 inch patio door roller

Thanks for posting. I'm afraid I'm going to need a little more information to be able to help. Could you provide a picture of the roller assembly you need to replace? And could you also confirm the height and width of the housing, as well as the diameter of the roller? This will help us identify what you need. Thanks.

Thanks for submitting these photos. We don't have an exact match for this part, but we do have a few that are similar. The main thing you need to be concerned with is the size of the housing; in your case, our 81-155 and 81-157 are similar, but they have different housing sizes. Please review the dimensions for both and see how they match up.

You'll also note that both rollers only have 1-1/4" wheels, not 1-1/2". We unfortunately don't have this roller style with wheels that big. The good news is that we sell the 81-272 kit separately; this allows you to install 1-1/2" wheels on either of these two products.
