I have taken pictures of the roller mechanism that I need replaced. Please send a reply email indicating the correct replacement from your company (please include part number). I will need 4.

Thanks for posting! I'm not sure if we have this exact roller, but please see our 81-125 Sliding Door Roller and compare it to your existing hardware to see if this can work as a replacement.
