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
