Thanks for posting! Before I can offer an applicable replacement for your roller, I just need to know a bit more information. First, can we see a picture of the wheels that go with this housing? Can you also tell us the wheel diameter?
Next, can you specify if the dimensions you mentions include the lip that runs along the bottom of the housing? Can you also give us more information on the inside cavity?
Good Day
I am looking for replacement roller and housing for a Vikings window. I do not have part number information. Attached are photographs of the part and my estimated dimensions follow.
housing OD 1 3/8" (l) x 1/2" (w) x 1" (h)
housing ID 1 1/4" (l) x 7/16" (w) x 15/16" (h)
roller diameter 3/8"
roller shaft diameter 3/16"
roller width 1/4"
Do you have a replacement option? Maybe your 87-190?
Your reply and assistance on this matter is appreciated
Mark
