<br>
I've got a client who insists on "plastic " ( synthetic) washers between SS washers and the aluminum racking and modules.<br>
<br>
I'm tried every angle to assure him it's not a problem to no effect.<br>
<br>
So anybody have any recommendations about type, material, and where to buy?<br>
<br>
Thanks<br>
