We believe you have an old style Keller patio door roller assembly. If the housing width is 13/16", the height is 1-1/8" and wheel is 1-1/2", then you can use 81-004 roller assembly. You definitely want to check those dimensions, though. It's hard to make out what they are, precisely, with just a tape measure.
