Replacement Roller for Older 4 Section Patio Door

A handy person from Chicago, IL says:
I have a house that was built around 1960 with a 4-section patio door spanning 20'. The 2 moving sections haven't really worked well since I bought it about 3 years ago. I took one of the doors off and saw that the small gears of the aluminum ratcheting mechanism are worn out, preventing me from adjusting the wheels once the doors are in place. Any idea where I can get replacements? I've also attached an image of the weatherstrip. Those seem to be missing of the material, so I'd like to replace those as well.

Thanks for posting. It's hard to tell. Looks like your second picture only has the inside portion of the roller unit, but fortunately, I see the outer housing in your first picture. Start with our 81-133 and 81-270 rollers. Both of these parts have the same lips at the end of the housing, like yours, which help keep the roller in place. Carefully go over the dimensions for both and see if either match up.

As for the weather stripping, start your search with our 58-042. We carry other types in different sizes that may work, but you can use the 58-042 as reference if it, itself, is not a match.
