Replacement rollers

A handy person from Costa Mesa CA says:
Is this product available in stainless steel or brass? This is for a marine saltwater application 81-090

Do you also have parts like the attaced images? The part with concave roller is about 7/8" w x 3/8" d x 1 15/16" tall and the roller is 7/8" in diameter. And the other smaller roller is about 1 1/4" long by 3/8" wide.Thanks,Noel Pepys

Thanks for posting. I'm afraid the 81-090 does not come in stainless steel. Your wheel also looks unique. You may be able to use our 84-050, but it is no longer available in nylon.
