Tandem Rollers for Patio Door

A quick learner from Northern Illinois says:

Please ID a replacement set of rollers for my patio door. The house was built in 1971 and I believe the door is original. The roller frame has stamped in the side " Product of Del Mar Eng Co. Long Beach, CA. Pat Pend"
This stamping can be seen in the photos attached. The rollers are metal, but seem to have a plastic coating on them or they have a metal core with molded plastic flanges. I see similar units on your website, but none have the 2 L-shaped hooks that position the part on the metal door frame.
Thanks for your help

Thank you for posting. I'm afraid this roller has been discontinued and is no longer available. You could consider our 81-084 as a possible replacement, but I cannot guarantee it will work. Check it out and see what you think.

Thanks for the suggestion. I saw this part when I was investigating my options originally. My only concern is the fact the door currently has a tandem roller and I was concerned about this single roller being able to handle the weight of the door. Do you have any thoughts on this?

It is possible that the roller may not last as long, yes. However it is the best possible replacement we have.
