Here's a roller I can't find on

A quick learner from USA says:
I am trying to find a replacement for the patio door roller assembly shown in the photograph here. I believe it may be a Klein but can find no other no information. The roller is: 1.75 inches dia and the housing 1.5 x 3 inches. Distance between holes in the attachment screw tabs is: 4.25 inches.

Does Swisco carry a product that could substitute?

Thank you for your assistance.

I'm afraid we don't have this complete roller unit, but could you get away with just replacing the wheel? If so, see our 81-116 or 81-237. Let me know what you think.
