Sliding door rollers

This looks like an older style Capitol patio door. They called it the "Ozark" patio door. We do carry a replacement roller complete with a 1-1/8" wheel, but your wheel looks like it is 1-1/4". Tell me: is the wheel the only thing broken? if so, you could get away with just replacing that and re-using the housing. See our 81-224, 81-228 or the stainless steel 81-241. These are all 1-1/4" in diameter. We also carry the 81-203 and 81-303 axles, but neither match up to your axle length of 15/16". You might be better off just reusing the same pin. What I do when repairing this type of roller wheel is to use a 1/4" pin like the 21-026B to remove the axle in the roller.
