glass door rollers

A quick learner from CT says:
Have old sliders from the 80s and currently need two new rollers. No identifying numbers however the handle hardware is stamped DORWAL. Please look at attached pic and see if you concur that 81-138 is probably the appropriate replacement. My wheel size is about an inch or inch and one eighth
thanks

Hello, Pete. I agree, the 81-138 looks like a good match. I would just go through our dimensions to confirm.
