idnetify sliding glass door roller

A quick learner from Houston, Tx says:
My house was built in the early 60's. Attached are 3 different views of the roller assembly.
*The metal roller itself had a plastic concave outer piece which has dissintegrated.
Can you identify the best replacement part so that I can order some?
Thank you Bryan B.

I should have said this part is for a sliding glass patio door!

Hey, Bryan. If possible, I would like for you to give us the dimensions of your roller housing. In the meantime, take a look at our 81-024 roller and see if these match up to your sample. The 81-024 has the adjustment screw in the middle at the back of the housing, while your adjustment screw is at the bottom. If the dimensions are the same as your sample you would need to switch holes in the glass door rail, using the adjustment hole for the frame screw and the frame screw hole for the adjustment screw.

Hi Dave,
sorry about forgetting to put dimensions in. I will do so when I get home. the 81-024 looks promising. Does it matter that the slot on my roller is diagonal as opposed to vertical?

Ah, I'm glad you confirmed dimensions. first thought of the 81-024 roller, but you say your height is 1-1/2", while the 81-024 housing is only 1-3/16" tall. It might not matter, but I'm not sure. Another suggestion is to just replace the wheel itself. Look at roller kits like our 81-266 and 81-272. See if either of these can work for your door.
