Thanks for posting, Sanjeev. I'm not sure what roller this is. I recommend you start by looking at our 81-05. Carefully compare the dimensions we show to your own hardware and let me know how they match up. If they differ in any way, please let me know exactly how.

81-030 at 1-1/4" or 81-138 at 1-1/8" look closer than the 81-05 at 1-1/2". To me his looks like 1-1/4"
