Sliding door wheels - markings: SR & SL

Hello,

Your roller resembles the 81-156, depending on how the specifications below compare to yours. Unfortunately, we do not carry the bracket attached to the top of the roller, which you would need to reuse if possible. Take a look and let us know if you need anything else.

You should be able to reuse that existing bracket. You might need to slide the bracket over to remove it from the existing roller. However, be careful when you try to remove it, since we could not find this bracket through any of our suppliers.
