Patio door rollers

Question

I want to change the rollers to an old aluminium patio door. I buy somethig but it seem to not be the same. What is wrong? Help me please.

Thanks for posting. When it comes to patio door rollers, the relevant dimensions are the height and thickness of the assembly, as well as the diameter of the wheels. Similarly, aesthetic differences can affect compatibility. Now I don't know your rollers dimensions versus the replacement you purchased, but that groove on top, as well as the tabs on the side possibly being more flared out, could all affect compatibility. Take a look at our 81-173. Carefully go over the listed dimensions and pictures and see if you think this might work better for you.
