Can I know the length of the top hole to the top right edge? (Product Code: 81-138)

My broken wheel is same as Product Code: 81-138. I just want to know the length of the top hole to the right edge.

Thanks.

Are you sure you have the 81-138? This looks more like our 81-155. Check it out and see if you agree.

Thank you for your reply. Can I know the length or the 81-155? 1-1/16" or 1-7/16"?

The distance between the center of the hole and the edge of the roller housing is approximately 1-1/16".
