To avoid a complete high-jacking the AFCI thread:

How about the availablility of the WR (weather-resistant) TR's (Tamper-resistant) and WR regular receptacles? Maybe a dumb question, but I am an Engineer and do not see the supply end, and it seems to me that corrosion resistant receptacles do not meet WR because it is a new listing?

In my web searching, it seems that only Leviton has a full line of TR's and WR's out, P&S has only residential, Hubbell and Bryant have promises of WR's, and Cooper's site is so miserable to search that I gave up (quiting time anyway). Am I right?
