Tandem rollers for a commercial door with a 1/2" housing

Hello,

Unforuntately, we can't recommend a replacement roller without seeing the original removed from the door. With that being said, you can start by looking over the three tandem rollers with installation tabs at the end of the housing that we've related on this page. These are just a few over many options. The design, along with the housing height, width and wheel diameter are all important factors to detemrine if one of them could make a suitable replacement. Also, take a look at the related videos. 

If you're unsure if one of them could work, feel free to send us some photos and dimensions of the existing roller to research your options further. Thank you!
