McMaster Carr is right on the money. They have a great search engine on their website, their shipping is quick and fair priced. If you don't find it online phone them they are very helpful on the phone as well.
Here is a thread on this subject from a short while ago. Click here...Looking for stainless grille mesh
DARBY WIRE MESH in business since 1854. They are the MFG of any kind of mesh you can imagine and they know what they are talking about
http://www.bwire.com/ They have a ton in stock and can ship same day. Very good price as well. Used them previously, take a look for sure before you go nuts searching elsewhere.
buy direct from the manufacture, go right to their place if you can, they could have an off cut piece that would work and will sell it cheap or just give it to you.
That is exactly right! That is the trouble when buying this mesh from mcmaster, they buy from somewhere else like: http://www.bwire.com/ So shop around and compare, and make sure you are not buying the same product, but paying more because mcmaster needs a profit.
