Tandem roller assembly for sgl

Question

I have a sliding glass door from peachtree ( I think), with 2 tandem assemblies on each of 2 slidin panels about 32 inches wide. The tracks are always dirty, and I've read that it's a galvanic reaction between the steel wheels and the aluminum track. The assemblies need replaced (pics attached) and I'm hoping to solve the dirt problem at the same time. Will the stainless 81-149 not react with the aluminum, can I use the 81-018, can I use a nylon version? Also, the entire opening is 10 feet, do you have track covers that long and would that solve the galvanic reaction problem? Thanks for your help...Tom in NC

Yes, our 81-149 would be a nice fit for a door near salt water, since its stainless steel. I recommend that you clean track when you remove the door. Use silicone spray instead of oil, as it will not attract debris like oil will.

I'm afraid we do not have track covers that long. You would need to butt together two shorter ones and cut off the excess.
