Searching for P/N 3684 roller

A quick learner says:

I have a Sunseeker boat which has a sliding door mounting 4
rollers made by P.E. Del Mar - P/N 3684, Model: AD1-323-LS (from their catalog). However, I am not able to find anyone who sells it and I was wondering if you could help either by pointing me out to where I can find them or if you could provide them for me. Please, let me know as soon as possible.

Kind Regards,

P.S. the items would have to be shipped to Italy

The part number you provided doesn't seem to be associated with any Swisco parts. If you could show us some photos of your part and provide some measurements, we can go from there. Thank you!

attached is the part I need, took from the PE Del Mar catalog. It looks closest to 81-004 with a 1-1/4" wheel.  The larger wheel probably won't hurt anything unless your door is really tight already.

Thanks for your help,

We do in fact agree with your recommendation; the 81-004 patio door roller would make for a good replacement. You may change the wheel to a 1-1/4" wheel, using something like the 81-224 with the 81-304 axle if that is the route you want to take. Since we do offer international shipping, I am sure getting these parts to you will not be an issue.
