I've noticed though when westfield does a pole renew with an A-frame arm, they tend to change them out to 6' 1 1/4" Upsweep bracket, also from Utility Metals. Guess the Utility dosen't want to mess with the big old A-frame anymore.
*UPDATE* I drove by this light today and it has been replaced with a 250 watt HPS 115. I've noticed alot of 115's popping up in westfield. It seems they may have changed to AEL now. I wasn't able to get a shot because I wasn't driving and the light was green while driving by.
I also noticed in google map there was some GE arms too...
