Grainger is a wholesale house and is a world wide supplier. Phone number is that of your local merchant; they list no 800#. Get the local yellow pages, or go to
www.grainger.com and find your nearest wholesaler.
Ought to be someone you know (if you can't) who can buy electrical/electronic parts wholesale. Usually, if person works for a large OEM manufacturing co, the local Grainger will honor their badge to make purchases.
